The tool includes everything you need for minor repairs on watches. I have to switch to shorten it up now in use had to steel bracelets un batteries. That all went without problems.
My experience: The tool everything works fine. Of course you have to work carefully and with attached power use it. Watches are now times Feinwerktechnik. But when I ran go to such tools as a blacksmith, then failed probably a more expensive set rather quickly.
Shorten Alone with now 5 battery replacements and 3x band I have the cost of the set already clean.
