does what it says on the tin

My son accidentally dropped one of his animal crossing edition joycons and the ZR button became unresponsive. After a while debating whether to send it off for repair or trying to replace it I decided to see if I could find the issue myself, it turned out part of the button inside had snapped. Purchased this purely for the single button as it was much cheaper than sending it for a repair or replacing it, was super simple & fast to replace it, included tools were ok but & did the job find but probably could have been a little better as the screwdriver bit kept slipping out but only a minor inconvenience as it still worked. Button replaced and have other ones spare in case of any future mishaps, money saved & child is happy he has his console back.
