The mouse is very convenient to hold and comfortable. It also feels high-quality to the touch. As for the battery, it only lasted two days the first time. However, the next time it lasted 20 days, even with daily use for many hours. The problem is that even though I've only had it for a month, the left button has already started to malfunction. Sometimes instead of one click, it gives two. Overall, it's a good mouse in terms of design, but I consider it expensive and don't see it lasting for many years.

Very convenient to use and immediate response to the buttons (also suitable for light gaming if you get used to its ergonomic design).

Unacceptable in terms of battery life. It constantly needs charging with a cable included in the package. If you are going to buy it, make sure to have a second mouse as a backup because this one will often leave you hanging.
