The ergonomically correct mouse I have ever used. Quick feedback with no lag. Amazing battery life and enjoy have quick button setups

This mouse is larger than what I was used to, but it's very comfortable when you're on the computer for hours. No fatigue. Provides a comfortable rest for your hand. It's nice too, that you can program it for up to 3 computers. So I can easily switch back and forth between my laptops. The only thing I would say is it seemed to have a little "drag". But I use a smoother mousepad and that helped. I would maybe rate it 4 1/2 stars because of the drag, but it is so comfortable, I gave it 5 stars. Would recommend.

Use with my Surface 4 Pro in BT mode. Responsive, rechargeable, long battery life and comfortable.

this is a very comfortable mouse to use (even though I use it with my left hand) and has alot lot of ways to customize the buttons etc. somewhat expensive. you can also connect it up to three different computers. I have two, one for the office and one for home

Great battery life and connecting it to my PC was super easy, personalizing the side buttons is a big plus. However, considering the high price tag I was expecting more from this product. It is not as precise as its name, at least not with my laptop.
