I have had it for about 8 months. From the first week, it had a problem with one part of the closure, but I didn't bother because I was able to fix it myself. Since then, it often breaks and I fix it because I was lucky not to lose the piece that comes out. Recently, it had the same issue on the other side of the closure. It has been losing time quite a bit for a month now, maybe due to the battery(?). I fix it and after a week, it loses time again. Overall, a very bad purchase, I would not recommend it.
