Only lasted a month.

Was so good for a moment and out of no where starts glitching and lagging horribly, making my job as an analyst quite frustrating. Unfortunately the window for replacement or return is closed now…such a bummer.

Had this for les than a month, and the scroll wheel is no longer functioning properly. I only browse the internet with this mouse, so i have not used this rigorously. But now when i go to scroll, it bounces the page in the wrong direction, then pauses before it may or may not respond properly. Typical Amazon sold junk.

It lasted under a year without issues then it was done working.

Nice ergonic design, function suffers. workers well for a few weeks then began to become very jumpy and track very poorly. save you're money and buy another product

Bought this March 2nd and it stopped working August 4th. The red light on DPI blinks but the bluetooth adapter doesn’t read. We tried directly connecting and using adapters for the bluetooth and using two computers, did not read. Terrible item.

I bought two of these. One of them, the scroll wheel malfunctioned in 6 weeks. Wont zoom hardly at all in and out. It got daily use for 8 hours a day. It also has some delays at times where they will not move freely. It will randomly occur and lags. Wish I could return them. Out of the 30 day return window.

Absolute junk. It constantly has trouble connecting. It’s laggy. It’s too small (and I have small hands). I wouldn’t go near this mouse.

As the title says, it was in expensive, but you also get what you pay for. I am not a gamer or daily keyboard assassin. I sit in the mornings and do a bit of internet surfing and email checking. Still, this is my third one of these and after light use, the buttons and the scroll wheel cease to work. I wouldn't recommend due to it's failures on all three I've purchased from Amazon.

I bought this product in April and was enjoying it, it was fast and comfortable to use. But a month from now I started having problems with it. Whenever I scroll down it bounces back and scrolls up, now it is impossible to use it. I tried changing the battery and the computer to see if that was the problem, but it was not.
