Worked less than a month. During the next work, screwing in the self-tapping screw, it stopped working, when the trigger was pressed (the battery is charged, the light is on), the cartridge with the bat stopped spinning. I wrote in a chat with support "we will answer you within two days by e-mail or call" I did not see a call or an email. At the moment, I took it to a service center, they said “if there are spare parts (which are difficult to find), they will repair them, if they don’t find them within 45 days, then Shurik is not repairable. Think before buying, but it’s up to you to decide.
