It's a very nice mouse but it's not for me. I'm very fidgety and am constantly accidentally clicking on the left side button that takes you back one page. I do like the sleep mode.

The reason why I gave it 3 stars is the mouse wheel, which I use a lot. When scrolling down a page, it will often jump back up the page, sometimes the length of how far I scrolled back to where I started. Even when it's not that dramatic it makes consistently scrolling through a page smoothly nearly impossible. I have another mouse from the same company (I believe the same model) and it has a similar problem but it's nowhere near as pronounced as on this one.

Buena calidad pero es pequeño y por esto al trabajar después de un rato la mano duele

For the most part this works. After a few weeks the roller balls skips, not ideal when scrolling all day. No issues with connectivity and all the buttons worked correctly. The CE mark is a fake though. All in all it got me through until I could afford a mouse/keyboard combo. Gave it to a co-worker that needed a mouse.

A little laggy. Thought it was the battery but it is not. I went back to a wired mouse

Standard function/performance, decent battery life, though the price reflects lifespan, mouse wheel stopped functioning properly after about 4 months

Me gustan sus teclas de navegacion, y su diseño, es muy práctico.

This mouse is decent. The only concern is: does not wake up my computer unless I click the left or right buttons, and it does not wake up my computer by moving the mouse. It's set up in device manager to wake up my computer, but doesn't wake it by moving the mouse

Ergonomics feel really good, especially with the thumb back button. The scrolling is starting to get bad. Looks like I ordered it July 31 and now November 7th, it's wanting to bounce the page as I try scrolling up. The page jerks up and down then holds me at the same spot in the page.
