I have had the mouse for a year. After the first 2 months, approximately, of use, it started to show several problems. Its battery doesn't last at all, and now I have to almost always have it connected to the laptop with a cable for it to work. Also, sometimes it doesn't even connect to the computer anymore.
The construction of the mouse is mediocre, as it seems that the material is not at all durable. Of course, something expected for the price it is at.
As for the positives of the mouse, I can only say that it is almost silent.

Very good mouse, charging is done quickly and it lasts long enough, with a full charge it easily lasts for 5 days. Also very accurate in handling. Highly recommended.

I bought it for my father who usually buys cheap mice and hasn't stopped complaining about them. Whenever I have used it myself, I have appreciated its ergonomics.

It's worth its money, for its rechargeable battery alone.

Update: 1.5+ years later, I have not a single complaint, EXCELLENT.

After almost 4 months of use, I am extremely satisfied! With daily use, I have only charged it once since I got it. It is incredibly convenient and has a great range of up to 10 meters, just as it promises. I highly recommend it :)
