The price was right 👍 and unit seems well made ..... works great.

Installing was easy. I have an HP laptop. I just slid the little USB doodah into place, put in a AA battery into the mouse, clicked on one of the mouse's buttons and it started working right away. No software to install. I like the optical eye. There are right and left buttons to click that work like the right and left buttons on the touch pad. Then there are two more buttons on the left hand side where my thumb goes; I am still figuring out what they are for. They both seem to be "return" to the previous screen. The scroll feature in the middle is great... just hover over what you want to scroll and start scrolling, even switching in between apps is seamless. As far as ergonomic, it is reasonable for me but not necessarily a perfect fit because I have large hands. But for someone with normal sized hands I'm sure it is very ergonomic. The price was definitely excellent and is probably the best mouse I've used.

Works really well, it does mention falling asleep in 8 mins of inactivity, you simply need to click and it'll connect again. Very light.

Used for general web surfing it is great. Second one I have owned. I do not game on my PC, so I can not comment on how it works for games.

I got this for the office and so far it is very nice! Very comfortable in my hand!

Best wireless mouse I have every used! I have one on everyone of our computers including my work computer. Very comfortable and responsive. The battery literally last forever. Highly recommend!

Price is super but the performance is even better!

If you are looking for an inexpensive ergonomic mouse this is the way to go.

This is a great mouse. It is small enough that it works well for travel, but big enough to use every day. The battery last a really long time. The buttons work well and the mouse is very responsive. The only issue I’ve had is after about 3 years the cover for the battery compartment cracked. The mouse still works fine and for the price it easy enough to just buy a second one.

There is a tiny notch on the right side to rest your ring finger. This allows my hand to relax while using it. It is definitely a right handed mouse. It's average size and fits big or small hands. My Amazon rechargeable batteries work in it. It is responsive for gaming, no lag that I detected at all, but I have a fast PC. I really like this mouse, perfect in every way. Weight, size and function and no annoying lights constantly flashing. It holds its own against expensive wired gaming mice I have bought, they are sitting in a drawer right now. Works plugged in to my PC switcher too. Rarely is a product this perfect. I hope it lasts with steady use. I am really impressed. I will probably buy a second one for a spare.
