I rate it with three stars rather poetically because the main problem is that the buttons were jammed and hardly worked at all, and the reason was that inside the orings and the internal threads were dry, with no grease at all. Fortunately, I knew how to fix it and now it works perfectly. But sending a product to a customer in such a condition, essentially non-functional because not everyone knows how to fix them, is a problem... also, it is not the same charm as in the photo, it is a bit different, there is no issue with that, I just mention it
