Powerful and inexpensive. Some limitations though.

I purchased the Celestron 71008 SkyMaster 25x70 Binoculars on a whim when they were available for $59.99. I already own several pairs of binoculars including the Celestron 15x70 SkyMasters. The 25x70 SkyMasters are very powerful, and have decent optics. There are several drawbacks though. The 25x70 Skymasters have a very narrow field of view, even compared to the 15x70's. For astronomical use, you're going to need a good tri-pod, as they are very heavy, and next to impossible to hold steady enough by hand. Even with a good tri-pod, the included tri-pod bracket is not very good, and will cause the binoculars to shake with any kind of vibration. The optics on the binoculars are good, but not great. In this price range, the optics are more than satisfactory. If you're on a budget and looking for very powerful binoculars, then I recommend the 25x70's as long as you know the limitations. Personally, I think the Celestron 15x70 SkyMasters are a better choice. They have a much wider field of view, and are a little easier to use without a tri-pod.

Edit: Just to add 1 tip. Regardless if you wear eyeglasses or not, if you roll down the eyecups, you'll get a much wider/better field of view. The eyecups aren't an issue on the 15x70 Skymasters, but rolling them down on the 25x70's makes a great deal of difference.

Great little portable shopvac for small talks such as cleaning up dirt or minor spills around the home or workspace.  It will easily take up dusty and light dirt and spills, but it does not have suction powerful enough to do a good job of sucking debris out of pile carpet or your automobile's floor.

DeWALT really should make more powerful 60V Flexvolt version of this device.  Even with a slight weight increase, I'd buy it in an instant!  This would solve both the power problem and the battery life (using the larger 9AH) problem.

Plenty of power, but not quite as quiet as I had expected.

Super powerful for the size. The only issue I had was the programmable switch was quite fiddly to change. Apart from that, very happy

For the price this is an excellent device, but there are limitations you need to be aware of before purchase. It seems to take great photos and good movies at least as good as my old GoPro Plus. Nice screen built into the back, the package is much smaller than a GoPro with the video back.
(a.) No user manual in English, only Spanish and Chinese. I was able to get one in PDF form by contacting the seller but it took an additional step and some time.
(b.) No separate battery charger. The battery charges inside the camera, there is no separate charger.
(c.) The charger is only European plug. If you have any type of phone charger that has a USB cord connection it will work, but none are provided for USA customers.
- The battery compartment is held shut with a very flimsy door that comes off, it is not hinged. A tether of some type would have been easy and smart.
- Protective case is difficult to open It locks with a sliding switch that needs to be activated while pulling at a 90 degree angle. Unfortunate design.
- Most GoPro mounting accessories are compatible, and this kit includes a good assortment of its own. Go Pro mounts all work perfectly.
- The remote control is a frustrating mix of almost great and you gotta be kidding. It has three clear and distinct buttons to turn the camera off, take photos or take movies. They work but you do not know if they did, it is a one-way communication. The buttons are clear to read and understand. However, if you use it in any remote setting  such as a helmet mount camera  you can turn it off but NOT turn it back on from the remote. You must push the front button on the camera to turn it back on, difficult if it is on a remote location.
- The software they tell you to download to use an Android phone as remote worked great with Android 5 on a Galaxy S4. You can do all functions from the android program once you get it to communicate.
Overall well worth the money but very in need of polish. I will know more once I get some paragliding photos taken!
Update: a couple months later, and it has been interesting. I am now using the camera more, and have resolved all issues except the nearly useless remote. Understanding the push buttons work as designed, but that they do not work as you would expect is important. a.) There is no feedback after you push a button if it has worked or not. b.) The "stop" button turns off the camera. Once you push it, the only way to start again is to turn it on from the camera itself. c.) if you push the "photo" or "movie" button, it stops whatever it is doing, takes a picture, and resumes what it was doing. It does work nicely with the remote software and your phone. Firmware is upgradable, just don't know where to check on it....

The Good: It has a reasonably long power cord. It's lightweight. It pumps even partially dry and has no issues getting a flow started even uphill through 10 feet of hose. It came with two different size attachment barbs so finding hose was easy.
The Bad: It's not as powerful as you'd think it was with a 400GPH rating. While it does seem to have a good head height it doesn't have a ton of power beyond 4 feet high, so upsize if you're expecting to actually go anywhere near the head height.
The Indifferent: It's a little noisy due to vibration, and the suction cups on the bottom can alternatively either not hold at all or hold with the power of a thousand suns. The power cord probably should have been twice as long as it is but that's just nitpicking.

I use this as an aquarium water transfer tool, and it works great in that capacity, draining buckets down to a water level of half the unit's height (~1.5") with no issues, but I would recommend the next size up due to slow flow if pumping upwards--it can take several minutes to empty 10 gallons into a tank with a pump height of 5 feet.

Very good power. the drawback if its hose is bit too short and easy to get loose from the joint. For the price, it work great.

The advertised wattage of 2800W couldn't be true. Other than that, it has great features. The included tripod stand is very convenient. The included mic sounds quite decent. Sound quality is good. Bluetooth, FM etc. works well. So good deal for the price. I haven't used USB and SD cards. I just play stuff from my phone over Bluetooth.

But their 2800W claim is so far fetched, that they should be dinged just for that. It hardly sounds like 800W, let alone 2800W.

It's good value for the money / powerful enough for size. Good deal / if you are looking for power this is not your best option.

Not powerful enough for the space needed, but really good unit no less

Overall the machine is good and powerful. Stays reasonably cool during long usage. The only issue is when using a cutoff wheel, the guard has to be removed which isn't a big deal considering that the guard's tool free design, but you just need to be more careful when in using a cutoff wheel. I would still recommend this product for intermediate level user that is not afraid of removing a safety feature. $9 more and you can have a case and another amp, but I didn't need it.

Pretty powerful considering how incredibly tiny it is!! If I had to go back and purchase this again, I might choose a slightly larger and more powerful one but this one should make anybody happy who is concerned about size. If you have a huge trunk or storage compartments and can go with a slightly larger vacuum, I'd consider doing that. As it is, this vacuum works well and is easy to empty and clean the filter. The cord is very long and it is highly maneuverable. I just wish it had more power! The nose extension is almost useless as their isn't quite enough power to suck up things from a cup holder with the extension.

This DVR is more powerful than the description implies.
1) Live video quality is better than the security video monitor
2) Records 4 inputs in quad-frame, quad-field, or mulitplex
3) Record by timer, alarm, motion, or manual
4) Programmable alarm settings
5) Programmable motion sensitivity
6) Four quality levels
7) Can be easily connected to computer for remote viewing/control
8) 80Gb HDD included and easily upgradable to 250Gb

The Cons are:
1) No Audio Recording
2) No cables or remotes are included.  Four video looping cables are required at $30 each and 1 BNC-RCA adaptor.  The second downside to the looping cables is the signal loss.  After 1 day, the video pictures began to flicker and defocus.  Probably the extra load was too much for the older cameras.  I ended up using the output slave of the video monitor and connecting it into one of the DVR BNC inputs.  The other three inputs are unconnected.
3) The hard drive is very quite.  Unfortunately, the cooling fan is not.  Personally, I would replace the cooling fan with another.

Overall, this DVR is great dispite the extra $120 and cooling fan.  Recordings are clearer and rewinding/replacing tapes is gone forever.  "Fire and Forget"

I bought this vacuum cleaner to replace my Hoover progressive, which stopped working after 15+ years!  It is a great little vacuum cleaner with lots of power but I gave it only 4 stars for a few reasons.
Pros
-Manuevers easily
-Onboard tools are easily accessible
-The air turbine attachment works great on picking up cat hair off of furniture

Cons
-I've used this Panasonic 4 times and, like other reviewers, I agree that it does have an oder when first turned on.  It's not nearly as bad as the first use.
-The telesoping wand is a nice feature but makes the wand bulky to get underneath some furniture, especially if the air turbine tool caddy is attached.  It would be better to be able to store this attachment along with the other tools.

Overall, I like it and would recommend it.

Very powerful considering its compact size. The only flaw is the absence of real temperature control. It's either on or off, despite the control on top. It ends up too warm if you keep it on in a small room, so I could not keep it on while sleeping at night. Otherwise, there is no complaint at all at this price.

This is a good cooktop, but its limitations should be understood. First, its output is equivalent to a 6000 BTU/HR gas burner, about the same as the smallest burner on a gas range. Note that this is far less than the "11,500" BTU/HR mistakenly claimed by another reviewer.

As such, it will handle small cooking jobs only. A quart or so of water boils quickly, but it will not handle the several quarts needed in a pasta pot, for example. That said, it does a nice job on small quantities of most anything, such as warming a jar of marinara sauce or frying a couple of eggs. In addition, its temperature control feature is nothing short of wonderful, making it great for chocolate or for holding a nicely controlled simmer.

With these limitations in mind, it's a nice addition to our kitchen.

Good combination of power and price. It's an older model but an old review makes it very popular. You won't find these on a construction site where Makitas and DeWalts rule but all my friends who handled it immediately noticed how much power it packed. Battery lasts for days or weeks. The main con is the plastic chuck that strips easily when rubbing against surfaces in tight spaces, and there's no indication how to replace it. It's not a heavy duty piece of gear but I expect it will last very long with proper handling.
