For the money spent, it is good, a simple mouse.
The point that concerned me is the hardness of the wheel, which often slips the finger. I opened the mouse, removed the wheel, and made scratches on the others, and the slippery surface became rough.
However, it is not as noisy as it is presented.
I have it for limited use on the television.
I finally opened it, added a little machine grease to the rotating axes, and its wildness subsided. It works like a Swiss watch since then.
All cheap things ultimately need their improvements to become more reliable and meet our expectations for quality performance

I have this mouse in red and white color and it has served me very well. I got it along with a Lenovo Netbook and so far it only has one downside. The scroll wheel! It squeaks like there's no tomorrow. The clicks are normal in terms of noise and quite responsive. I don't use the DPI button but it's good that it exists. The mouse, after about 5-10 minutes of inactivity, automatically shuts off to save battery, since there is no on/off switch. Lastly, the plastic shell of the mouse is quite thin, allowing the light from the "laser" to show through, it's a joke! Overall, for its price, it is very good. Decent quality (excluding the scroll wheel), portable, comfortable, and beautiful. However, I wouldn't recommend it as a permanent solution. It was a deal for me, along with the laptop, so it just worked out. Later on, I will get a better one from Logitech, the M220 Silent.
