Very nice appearance, perfect color. Connected immediately with ASUS computer via Bluetooth. I don't have an opinion yet on the battery life, but I will update at some point (it already had an AA battery inside). For now, the sound of the buttons doesn't bother me (it's not silent, but not annoying either).

When it finds the bluetooth immediately, it's great. If it gets stuck and can't find the laptop, it takes a while to close and reopen the bluetooth to locate it.

The only thing I have to criticize about it is that when it is idle and I go to use it for the first time, there is a slight delay until it "unsticks" and moves, as long as it is already in motion, everything is fine. I don't use it for gaming, just simple office work.

The keys definitely make much more noise than expected, and I would say even more than a regular mouse... I had a cheap wired mouse until now and it was perfect in terms of this feature. Other than that, because it is Microsoft, it is very compatible with Windows (as soon as I removed the battery sticker, my computer instantly recognized it) and overall it responds well to movements. For its price, it's fine.

(In response to those wondering: it takes a battery, it is not rechargeable)
