This is a great tool, very easy and simple to use, once you get familiar with it's operation idea, that's all... perhaps it should come with a simple instruccion sheet (actually it doesn't)!!!
Yes,It might be made from cheap materials, but it really gets the job done!, and I think that if you take good care, it will last for a long time at your service!! So I've already adjusted 3 watches, that could have cost me almost triple in a jewlery store, that the price that I paid for this simple tool... I mean, it really worth the price you pay for it!... and the best of all: YOU COULD DO IT YOUR SELF!!!
