I was pleasantly surprised by this mouse. It contours to my hand very nicely. It feels good when you’re using it. It’s very lightweight. I didn’t do any extensive testing on this like professional testing from what I can tell. This is very accurate when I click and when I move. You can easily change the sensitivity setting by the button underneath the middle mouse button. The last good amount of time I primarily have been using it plugged in though, but at least I know I can take this with me and it be ready to go. This kind of performance for the price. Read more

This mouse is the opposite of "all show and no go". It's very plain and ordinary looking, but brings it with some good features- and a couple drawbacks as well. + Only 54g- this is pretty light considering it's wireless and not made with a honeycomb or skeleton shell + No 'gamer' RGB lighting effects (yes, I made this a plus) + Decent PAW sensor- not the 3395, but performs well enough + Super flexible USB cable included + DPI can be changed with top-mounted button- which changes LED color to indicate which DPI setting is chosen + Polling rate can be changed with a bottom-mounted button. There is no indicator to tell which rate is selected tho + The protective film on the skates have "remove" printed on them. This is nice, since a lot of people probably don't realize there's a film that should be removed for smoother gliding. + Can be configured through software, but I did not try it. I'm pretty cautious with installing software from unknown companies on my computers. - No wake on motion- must press a button or scroll the wheel to wake - Dongle dock door could be easier to open - Wheel does not have extra switches for side scrolling - Little hollow sounding and main button clicks could be quieter. Scroll wheel is quiet enough. Bottom line, very good mouse for the price. It performs well for productivity work and all but seriously competitive gaming. It's sedate appearance makes it suitable for office use. Read more
