Got this as a starter mouse as I slowly build up a PC set up again after decades. For now, I’m simply mirroring laptops to a screen and didn’t want to be held to the built-in track pad while exploring on a larger space. I liked that the mouse had the color shifting (matching a keyboard I got too.), but now that I have it, I wish that I could either stop or select the color, rather than it shifting constantly. Though over all I rarely notice the color shift unless the mouse has gone to sleep. Being able to pause or stop the color option would probably help with battery life. Speaking of Battery Life- I’ve had this about a week now and seem to need to charge it every two days, which given how much I’ve been using it isn’t too bad really. I stay on it probably about 8+ hours through any given day. Performance is smooth. Be sure to play with the speed when you get it and see what works best for you. At first, I thought it was lagging till I played around. Got it bounding around faster than the Energizer Bunny now. It really is quiet; I sometimes double click cause I’m not sure if I already did. The buttons have a seamless look and are easy to press down without too much force, but not light enough to too many mistakes. Love that it’s Bluetooth, didn’t have any problems with it connecting right away. USB 2.5 works smooth too, I don’t see much difference between the two connection types which is really nice! Overall, it’s a wonderful starter mouse that I didn’t expect to like so much. Originally, I got it because it was fairly cheap and assumed that I would just chuck it one day when I upgrade, but I have a feeling this little guy will be around for a while!
