Would not recommend these, your thumb ends up sitting at a odd angle so at the end of the day your arm and back end up hurting

The size is big enough to support my hand. The movement between device is quite smooth considering I'm not surface laptop user. The software also help me to adjust the button for my need. The price is much more cheaper than it's competitor and good color too. Sometimes I realize there's some lag, but doesn't really hinder my work.

Great product, really comfortable and well constructed.

Overall it is a great mouse. Really comfortable in the hand and great if you are using your device for over 30 minutes. It would be better if it came with a left handed version for left handed people.

Using this mouse with my mac, haven't had any issues with it, very smooth and comfortable in my hand. I do use it with my right hand, so if you're using it with your left hand it won't work very well. Haven't had any connection problems so far. My mac detected it as soon as I turned it on and it connects very fast every time I move the mouse from sleep mode.
