Started to develop carpel tunnel and was affecting my gaming and computer design work. Looked around a lot and ended up getting this over the very expensive logitech. After about 6 months of use I'm very satisfied with this mouse, but its not without its faults.The good:-Extreamly light weight, thanks to the rechargeable lithium battery. This is an extreamly important factor. The heavier the mouse, the more strain it puts on your wrist. This weighs like nothing and I like I don't have to think about replacing batteries.-Glides smoothly with little resistance. Also important to minimize wrist strain.>Ergonomic feel, and buttons all feel great. Took a little getting used to, but it feels good in the hand. Still sometimes miss put my thumb though. All the buttons work with no issue or miss clicks.The bad:-The highest dpi setting is lack luster compared to my logitech gaming mouse. The lowest setting is very low and I never use it. In fairness that's a pretty niche complaint.-The usb signal can get sketchy. When originally plugged into the front of my computer, about 4-5 feet away from my mouse there was a noticeable delay and lag; especially gaming. However when I plugged the USB dongle into my keyboard, there was zero lag. Also the usb slot to hold the dongle under the mouse is a joke. Doesn't hold it in place at all, so isn't somthing I could use with a laptop on the go without fear of losing it; it would need to remain in the computer.Overall though I would recommend this mouse. Since I've been using it my carpel tunnel symptoms have subsided. Doing all the other things for it like mouse/keyboard cushions, and wrist compression helped, but getting this mouse was the key. I wouldn't be able to use the computer without it.Please make a gaming version of this mouse, since a lot on the ergo market for those break often.
