does what a mouse needs to do and not overpriced like other brands

I bought this to replace a wired one while I work at the kitchen island, but unfortunately it does not work on the granite counter top like the wired Optical one. It works on a desk just fine but not what I wanted it for.

The mouse does not work well. It is very hard to scroll. Response is slow. Could not use it. Not recommended.

At first it didn't work consistently on the regular table surface, so I put it on a mousepad and it was great. Then days later it suddenly works just fine on the table. But I have even more confidence that it will last longer than the one it was replacing. I'm confident in what Monoprice sells. Thanks again.

I've owned this product twice and both nice we're ruined by a simple drop on the floor. Terribly fragile for a travel mouse.

Works well. Note that the usb receiver is shipped in the bottom of the mouse, not separately. Has an on/off switch and automatically shuts down with disuse.

Works well no fuss no brainer to use

Bought it to go with 25 oz water bottle in which I love love love
Definitely would recommend for that bottle

I have purchased 2 of these and they worked fine until accidentally dropped. After that the cases were somewhat loose but they each functioned fine for another 6 months or so. Another problem is that one of the springs for the negative pole of the AAA batteries is prone to bend to the side and can ultimately lose contact with the battery. Nonetheless they are sometimes a great convenience and I am ordering more.

The auto-sleep feature is a bit surprising if you aren't expecting it, but it is actually quite handy.
The sheet of paper in the battery bay is to help remove batteries, and should not itself be removed.
The solder work on the boards are a little wonky, but not bad considering that this is the lowest priced mouse I could find anywhere.
Both mice I received work without any issues, and batteries are included.
