The fork is not suitable for multiple changes, you is me aborted after the second use of the UN on 31 day 1 after the return period, where I could return this product. The product has broken off the top, which at various watches also requires greater pressure, so the burden is also correspondingly higher. Too bad that I can throw away after two uses of this product, because you could be making it directly from him to watch specialists and 5. Anyway, I am disappointed by the "professional" tool.
