Works well, Battery life so so, trigger is Junk, but I am a Mechanic who demands a lot from his tools. All in all for the money it works well.

Works pretty good, battery lasts me around two weeks. My only complaint is; as it's nearing the low battery state, it repeatedly interrupts whatever you're listening to, every few seconds with, "Low battery. Please charge." Which is probably a feature, and not a bug.

Works well once you get used to it. As others have mentioned, the signal is affected by how you hold it, and it doesn't work very well if you have your hands covering the edge which points away from you. Also, as one of the prior reviews mentioned, the touchpad is kinda grainy, and it reminds me of some of the early touchpads when they first started putting them in laptops (remember the good old days of the nub mouse with no touchpad? Yeah it sucked....)

No word on the battery life yet, I've only had it a couple of hours. If you see this review months from now and it still says this, you can probably assume I was happy enough with the battery life that I didn't see a reason to come back and complain.

These triggers are great, I've been using them for about two months now and only had to change the batteries once! I use these Everyday and they haven't failed me yet. Great product. I recommend.

This mouse works very well and is definitely worth the low price.  I subtracted one star because it doesn't turn itself on just by moving it, only with the push of a button.  This seems kind of petty but I have other mice that instantly work as soon as you bump them and I'm not easily getting used to starting with a click.  The manual claims this is for battery saving but the batteries in my other mice last well over a year so I don't think the push to turn on can use much power.

Works fine.  To use the secondary trigger you need to use a cord to connect the battery case to a port, but that is probably a limitation of the camera.

Works great as expected. You get a good overall average on your trigger pull.

I've had this unit for about a year and used it a lot with my Sony A100 (with hotshoe adapter) and Alien Bees strobes. Has worked flawlessly. Only drawback is no way to change battery in transmitter (receiver takes 3 common AAA's) if it dies. In a year, I've replaced the AAA batteries three times. Recommended as a simple yet functional remote trigger.

Nice mouse, works functionally. LED's can be a bit annoying though, docked one star. Also what is that sensor?

Changing this review, but I'm leaving the pictures of the mouse feet from the initial sending. Still rather upset that I had to get it replaced, but I'm at least happy that Amazon's replacement policy works pretty well. As for the mouse? It works well too. Nice smooth motion, very solid-feeling buttons, and not overly loud to boot. The side buttons are a little awkward at first, but it shouldn't take too long to get used to them.

I'll admit, I don't really notice much difference between performance mode and longevity mode when it comes to how it moves and feels. The DPI changes are one of the most obvious-feeling buttons I've ever had for this function. Usually it's something out of the way or annoying, but these ones work really well. The wheel has a soft-feeling "click" to the scrolling, unlike the harder-edged feel of most mice. This may or may not be to your liking, but I always want something a little between the hard clicking and the completely free-spinning motion of my M705.

The mouse is a bit heavier than my M705, and a fair amount bigger. If you don't have bigger hands, you might have a little trouble operating it. The sides are a little slicker than I like, but I'm sure that as they wear a bit, they'll get more rubbery. They clearly tried, but with drier hands, it just slips a bit too much.

Now, it doesn't have some kind of li-ion rechargable battery or anything, but AA batteries are a good substitute, since they're pretty cheap to buy more of.

I'm not particularly fond of receiver being pretty much only for this mouse, but it works fine with the mouse. I just wish I could use it with the other wireless devices I have, but now I'll just need to have two plugged in, like any other pairing.

Altogether, nicely done. We'll see how it holds up!

The power and recycle times are great battery last forever lol. didn't like that some times it won't register with the brand probably a problem with the x1 trigger though

Does exactly what it says.  It's sturdy, and fairly easy to program.  It really sucks the battery life though.  I put some rechargeable AAA batteries in and before the day was through, the battery alarm started going off.  I changed the type of battery and disconnected the annoying alarm.  Waiting to see how long the batteries last this time.

Works okay the trigger wiggles very easy compared to my other ones, if you don't keep your finger pushing it forward during your draw back might fire on you to soon

This product works reasonably well; however, the battery life is fairly short.  We hung it in a bush next to our neighbor's fence, directed toward the neighbor's yard.  It seemed to decrease the nuisance barking of the neighbor's 4 dachshunds.

It works and charges well on Dell 5748, but can not use the Dell extended battery life options in the control panel, and can with the genuine dell battery which is the only reason I only gave it 4 stars. Considering I could get 5 of these batteries for the price of 1 from dell, I do not think the dell extended battery life options will extend it that much. For the price, it's a bargain.

I love this little controller. I've used it at least a few hours a day since I purchased it. The battery life is great and has the added benefit of charging your device while you play. My only real complaint would be the triggers. They are very stiff and don't have much range. In the end its not a deal breaker and I would highly recommend this to someone who plays a lot of mobile games
