I got this on prime day when I needed a mouse with the two extra buttons on the side. So far it is working well and hasn't had any issues. For a cheaper model, I am happy with what I am getting for the money.

the mouse itself is fine, but the pads on the side will get really sticky if you leave your mouse in a hot room. seems like whatever they use to glue the pads on the side will melt and get squeezed out as you use it. extremely hard to clean the sticky substance too. may want to rip the pad off when you first get it, clean the glue off and use superglue to stick it back

This mouse lasted for about a year and a half, now it has issues when you scroll with it. It will erratically move the screen up and down instead of scrolling smoothly down.EDIT: After I left my review I was contacted by customer service and given a refund. I’ll add a star for good customer service from the company.

I purchased two of these mice and put them both into service around the same time. One of the two works well... no noticeable issues with pointing, clicking, or scrolling. The other mouse started having issues with the scroll wheel not long after I started using it. Physically, it feels like it is scrolling properly, but unfortunately the scrolling on screen is jittery. The best way I can describe it is that it scrolls in the intended direction, but often scrolls back in the opposite direction, even if the wheel is only rolled in a single direction. In any case, even though the scrolling physically feels okay, I suspect a mechanical problem of some sort. At some point I hope to open it up and see if I can fix it, although there are no obvious screws on the bottom of the mice. The base of the mouse has two small circular pads on the side away from the wire and one wide pad on the side close to the wire. It's possible that the screws are hidden under those pads, which will make opening it up a bit annoying.Another complaint I have is that the padding below the two side/thumb buttons was "bleeding" a sticky film or residue. This residue was not easy to get off, even with all purpose cleaner. Eventually, it more or less went away on its own, but I'm still not sure what caused it... perhaps the glue used to affix the padding?Keep in mind that the cable length is only 5 ft. One of the mice I use with a laptop, so the cable length is fine. However, the other mouse I use with a tower that sits off to the side of my desk. I had to use a spare USB male/female cable to get enough length for comfortable usage.For anyone who is curious, these mice are Made in China.Ultimately, I was a bit disappointed with these mice, but given the price I can't complain too much. Most of the shortcomings I can live with, but the failed scrolling after only light usage is the most frustrating of the flaws.

It's all right for a mouse. The minimum DPI is already too high for me. And the clicks are definitely not on the quieter side. The light on the wheel always is on, and bugs me quite a bit.
