... replacement to use with SLKZ tennis trainer and it sucked. First off
345078
I purchased this ball/cord replacement to use with SLKZ tennis trainer and it sucked.

First off, the cord is about 1/3 shorter (5ft or so) than the kinect cord that comes with the base. So the ball won't travel as far.
Second, the cord is less elastic and won't stretch as long, thus making the ball feel very hard
Finally, because of the above two, the base becomes unstable and moves randomly when you hit the ball, which in return makes your ball's trajectory unpredictable and hard to hit.

So here's what happened when I replaced the default kinect cord with Tourna one. The ball bounces back weaker, more unpredictable and giving you less time to react

After 2 months of light use, this glorified tennis racket stopped working. It was fun while it worked but now the grid does not electrify. I've hit many flies and nothing happened. I know my swing could be off but after a bunch of tries with no ZAP, i tried it on myself. And didn't feel a thing. Of course it's out of the Amazon return window and although its supposedly under Warranty for a year, the company refused to return my 2 emails about getting a replacement. Dont waste your money with this cheap quality item or their shady company. Pathetic.

I have an old dyson animal that after 5 years started making too much noise around the beater bar.  Decided it was time for a new one and was glad to try the ball option.  Went for the top of the line animal, dc65 pet.  The first one simply stopped sucking, within the first month.  So I figure I got a lemon and exchange it for the same model.  That one would get fur, that is pet fur around the beater bar and the bar would stop moving.  I called dyson and they told me the new plastic they used was for the beater bar, instead of the old metal, was causing this.  They asked if I had pets, I said yes and they said that was the problem.  I said this is your pet model for crying out loud.  Within two weeks, this second one also snapped/disconnected at the ball and suction stopped.  Between the failing product and lousy customer service, I would give it no stars if I could.  The old dyson animal got the job done and lasted just beyond the warranty.  I ended up getting a hoover windtunnel for just over $100 and figured if it lasts a year, then it is equal in price to a dyson.  Unfortunately, that is all I got out of it.  I would really love to hava a vacuum that can work great in a home with dogs with mid length fur.

3 days ago i lost my original mic for the Sennheiser ew 100 g3 and read the reviews for this and bought. i needed a replacement asap for the next day so i purchased this .. boy i was strongly mislead & when i shot a basketball training program i had to trash all the footage because this mic caught a whole lot of wind noise (even indoors smh) . i know the price is a lot cheaper but you really get what you pay for with this, garbage. just buy the Sennheiser replacement . in the long run it will pay for itself.

I bought this from my local Dick's Sporting Goods store with high hopes to begin sandbag training this weekend after my football games. I own no fewer than a dozen different SKLZ products, and this is the first one I've ever returned or been so frustrated with that I kept it for less than an hour.

I bought this, picked up 50# of general sand filler from my local Lowe's, and began to fill the 4 included yellow sandbags. I poured out the sand, carefully measuring & weighing each pouch to a near-perfect 10#. Then, I attempted to fill the duffle bag with the weighted sandbags -- alas, they do not fit once full.

Here's the problem: the yellow insert bags are longer than half the length of the duffle bag and wider than half the width of the bag. What does this mean? Well, when filled they do not fit into the duffle bag and enable you to zip it up. HORRIBLE design. This is a very simple concept: if you intend to fill a bag with other bags, make sure that the maximum volume of each of the four insert bags is no greater than 1/4th of the entire outer bag's volume. Simple.

I returned it. Dick's associates apologized to me, politely, but this isn't their problem. The designers at SKLZ need to take this back to the drawing board. I'm on Amazon.com right now to order a different, better bag.

UPDATE: SKLZ has posted videos on how to "properly load the sandbag", which, in my opinion, doesn't fix the problem, but at least they acknowledge the issue and attempt to address it. However, this still needs a complete redesign/overhaul before I can recommend it. You should **NEVER** force a consumer to conform to your product's design, but the product design should **ALWAYS** conform to the needs of the consumer. As such, I will not be a consumer of this product. I'm gracing this review with an extra star (from 1 to 2) for the effort, though.

I bought my Avitron V2 and could not get the bird to fly higher than 10 feet or so and it lost signal and stopped flapping after about 12 feet of distance. The next flight, the controller  turned off on its own after the first four seconds or so of being turned on, followed by a bad electrical smell from the controller.

I returned it and bought a second one from Amazon and the exact same thing happened with the controller before the bird was even able to get into the air for the first time.

I have to conclude that this particular version that is being sold on this site is a cheap knock-off from the original Avitron V2 -  will find another vendor to purchase this from as the videos I've seen are pretty awesome when it works  as designed.

Never having used clipless pedals before, I bought the Eggbeater SLs based on the recommendation of a friend and all the good reviews I've read. Unfortunately, they feel sloppy and there is a lot of play in the pedal to shoe interface (yes I have them adjusted correctly). I realize that some slop is desirable and maybe I just need to get used to them but I am disappointed because they do not give a confidence inspiring feel. I do not feel any more "connected" to the bike then I did with platform pedals.
  Also, at one point I was trying to clip in at a stop light and managed to smash one of the pedals open (one of the wings slipped over the spring allowing the pedal to become flat rather then star shaped) so I was in the middle of a busy intersection trying to figure out why I couldn't clip in. When I got to the other side I had to get off my bike and pry the pedal back open with a multitool. To me, this is a huge design flaw.
  If I could do it over again I would have gone with the Time ATAC Alium. I think they have a much more reliable design.

I chose this trying to avoid the 'Diamond Tester II' model purchased previously which was faulty on opening, cheap and shoddy. I  thought by paying double the price I would at least get something a little bit better made. I was conned, this is not the same one in the picture.

It is exactly the same Diamond Tester II model I was avoiding. The box sated Delux Jeweler's Edition Model P7 inside the box is 'Diamond Tester II'

Don't be fooled, this is cheap rubbish at double the price of cheap rubbish. I will be returning mine as soon as possible as it didn't work upon opening and when  I did get it to work it  flickered on and off showing a terribly bad connection problem.

Seriously miffed that someone can show  one product for purchase  and send another.

This product was awful. From the moment I took it out of the box it was one big headache. Let me first start by saying I consider myself tech savvy. The set up for this product was a nightmare. It took many attempts until it was able to sync the watch and have it reflect the appropriate time. The app synced to my iPhone's internal step tracker, but never connected to the watch (even though the display indicated that it was synced). So the app counted steps, but only those recorded when my phone was in hand. The second dial that was intended to display the number of steps recorded never worked. I did reach out to the company. They suggested a factory reset (hit reset button 5 times) and an app reload. Both were done numerous times. Still no step tracking by the actual watch. Not to mention, the customer support is via email ONLY. So response time varied from 2 hours to 4 days. Unacceptable. I returned this item as quick as I could. I wanted to love this item. It's design is beautiful. It's discrete look is unmatched in the fitness tracker world... But it never worked and customer service was less than helpful. Big 1 star from me. Buyer beware!

This is a cheap knock-off that can't perform as the game is intended.  The first one we bought was missing a Velcro strap that attaches the net to the frame so we returned it to the store. When the replacement set was assembled, the plastic frame cracked under minimal tension from the net. In addition, the bounce action of the provided balls from the net was so minimal that it was nearly impossible to volley.  We will be returning this to the store and will replace it with a actual Spikeball set.

I got knockoffs so I decided to but from a better brand. But I guess LG is really not better. Opened and used for two days. Went to check visual voicemail and it interrupts my playback and then says "Call Ended" in an endless loop. Put my knockoffs back in and they handle voicemail fine. I'm returning these LG earbuds and moving to a different brand all together. Disappointing.

I've used two of these controllers now, and in the end, if I could rate 0 stars, I would. I bought this because it's bluetooth and supposed to be gaming grade, and I needed a better controller for the PC for my racing games, and I wanted one that also worked on my galaxy s7 for the oculous headset. Well I managed to get maybe a half dozen uses from both controllers totaling about 2 hours all together per controller before they tore up beyond use. Both triggers and also the sticks quit functioning as they are supposed to and would go haywire as if I was mashing random buttons and triggers and moving the sticks around.

I'm not one to abuse my electronics either. When it wasn't in use, it was kept turned off and placed under one of my monitors so it was out of the way all together. So for it to tear up so easily with so few uses, and on top of it, both controllers tore up in the exact same way, this was not just a random factory defect.

The controller software for the PC is also horrible. It doesn't allow you to customize buttons or even preform a test of the buttons and ranges of motion for the triggers and sticks. It has a live test feature that shows you how everything reacts when you preform an action so you can change deadzones or alter what a button does, but it doesn't actually let you do anything.

As such, I do not recommend anyone waste their money on these controllers.

Sadly, I had heard from many how SteelSeries was such a great company and has high end gaming equipment, but this has only proven they manufacture garbage. My old Logitech F710 was superior to this controller and it was horrible with connectivity even...

Down two stars - see the update for why.
-----------------------
Too damned big - the size of a 1970s tennis racquet. But for some reason, all of these zappers seem to be enormous - is there some reason a smaller, discreet unit cannot be made to carry while hiking? I don't need to kill every gnat in the forest, just the one buzzing beside my ear. But since as far as I can tell this is no bigger than any of its competitors, no star off for that.

One star is deducted, however, for the poorly situated battery door. When you hold this as designed, with your thumb over or ready to be over the power button, the sharp corner of the battery door digs into your skin. Not a big deal at all for just picking it up to zap something flying in your bedroom, but quite tedious on long walks. A leftie will definitely find it more comfortable since the door would be facing away from their hand.

That being said, this thing is POWERFUL and it has a fine mesh grid that evaporates the smallest of no-see'ums. I've only had two get through unscathed but they still got smoked on the second pass. It's so powerful that with smaller insects there isn't even a dead body left, just a puff of smoke.
-----------------------
8/7/14 update: actually, I did find a smaller one, the racquetball racquet-shaped OneShot <http://www.amazon.com/OneShot-Mini-Hand-Held-Zapper/dp/B00H08IM3M/ref=cm_cr-mr-title>, but it has its own problems.

After ten months and maybe three hours of total use, both of my Zap Masters started having the same problem, within one week of each other. It started out as a slow clicking sound and rapid loss of power, barely zapping anything. Replacing batteries temporarily restored zapability, but also made the clicking faster and louder. I figured something was shorting the grid but couldn't see anything, so I removed the batteries, rinsed them under a stream of water, shook them dry, and repeated. One came back to life, at least for now, the other one lights up but no power to the grid - into the trash. I'd rack this up to a fluke if it weren't two units right after one another, as if they were designed to die on cue. Still the best one around when it works, and I'll have to see if my new slightly smaller unit lasts any longer.

I hate giving this product a "one" because it is a terrible piece of equipment!  The first one delivered didn't work because the beater bar wouldn;t rotate.  The replacement failed in less than a year: again the beater bar was defective.  I went online to order a replacement beater bar and was informed it would have to be back ordered (long waiting list).  After a month I called to ask where I stood on the list and they said it would be another 3 months before I could expect a replacement. They wouldn't offer any special compensation for a replacement vacuum cleaner.
With such a long waiting list for this part, it's obvious there are defective engineering and/or poor quality control issues with Hoover products.  I would warn all customers considering buying a vacuum cleaner to avoid Hoover products!

First off the instructions are sorely lacking.  They state if you have a dedicated line for a suction cleaner the instructions will be later in the manual.  Oops they must have forgotten them, just like they forgot to provide some type of fitting to connect to a dedicated line.  For this purposes of my test I used the connector provided for a skimmer connection which looked horrible. Unfortunately my current adapter from my dear departed Barracuda G2 would not work. They also included a plastic wing in the box and on the pictures, but no where in the manual does it say to install or its purpose.  I tried both with it on and off with the same results.

Now on to results.  I fired the thing up with the weights as the manual instructed and it happily when straight to a corner where it stayed.  So I fiddle with the weights and it moves along the edge right to the next corner.  Play with the weights some more and off to a third corner.  I tried at least 10 different combinations of weights configurations to no avail.  Mind you this is not a large difficult pool.  It is only 11,000 gallons with a maximum depth of 5 feet.  With at least 10 hours of running time the thing never saw the middle of the pool or stayed out of a corner longer then 15 minutes.  I have a variable speed pump that is set to 2900 gph which is 48 gpm, much more then the stated minimum of 28 gpm in the manual.

Back to Amazon for this one.

I purchased this trainer to be able to hit and rally even when I didn't have another person to play with. I was not ready to invest in an automatic ball machine, so this was a cheaper alternative. It takes some time to get the hang of the trainer. You have to hit very hard each time to get enough bounce for the ball to come back the same distance. After using this trainer, I started hitting almost all of my balls out of bounds in the tennis court because I was used to hitting with the sole purpose of hitting as hard as I could. I didn't want to use it anymore because it seemed to be skewing my sense of how to aim inside the lines.

I have tried for years to control one of my dog's penchant for "idiot barking" (barking for no particular reason) and decided to give the HAVAHART ULTRASONIC BASIC TRAINER a try before re-investing in the only that seemed to work ... a shock collar.  This type of training device proved to be ineffective on resolving my dog's problem ... for the most part.  I am not sure whether the ineffectiveness is due to a faulty device, my dog or the technology itself.

This training tool is a hand-held device (has no collar associated with it).  It basically is a conical remote with the flared end serving as a speaker.  The HAVAHART ULTRASONIC BASIC TRAINER is designed to overload the sensitivity of a dog's hearing as a means of correcting behavior ... supposedly a more humane way of behavior correction (as opposed to a shock collar).  This device has five different frequencies to choose from and the goal is to find a frequency that alerts your pet.  The sounds generated by the device are fairly inaudible to humans unless the room is completely quiet or you place near your ear (the sound is akin to the "clicking" of static electricity).  The trainer can be manually activated with a button or set on "auto" where the sound of a bark should rigger the device.  After using all the frequencies and settings, I found the trainer to be useless in stopping any of my dog's "idiot barking".  Some of the issues I have with the HAVAHART ULTRASONIC BASIC TRAINER are:

- It is difficult to determine the status of the device at any given moment.  A red blinking light serves as an indicator for several modes:  setting, auto and power on/off.  I couldn't even tell if the thing was on unless I stared at it long enough to detect a light blink ... then I had to wait in order to determine if the blinks alternated to determine what mode it was on.

- The frequencies range from a low to high "ticking sound" and some have a slight squeak/chirp.  A frequency with the squeak/chirp was most effective on my dog, but I noticed the squeak/chirp always reverted back to the standard, less-effective "ticking" sound.  I don't know if this is a glitch with my particular trainer or not.

- To be honest, I find the normal levels of noise in my house (with appliances, heat pump, television and kids) overloading my own hearing, let alone a dog's sensitive hearing.  I discovered on "normal" days, the dog never even noticed the trainer being activated, even directly activating it.  Only when I moved it close to his ears did he respond ... by barking more.

Overall, I was not impressed with ULTRASONIC BASIC TRAINER and I'm a bit skeptical as to the effectiveness of ultrasonic technology.  A silent environment may allow it to work better, but that seems impractical.  I have two male yellow labs and while my aim was to correct the behavior of one, I noticed the other dog never reacted to the device when it was used in the same room ... the spoke volumes to me.  While this trainer did not work for me, I cannot definitively say it won't work for others.
