For its price and small tasks, such as battery replacement, it's OK.
I don't think its quality will withstand more use

Cute for basic tasks of changing batteries in simple watches. Not very good quality of components for more demanding tasks. Expected though since it is cheap. The good accessories are owned by watchmakers. However, very good for simple tasks such as changing batteries and adjusting metal straps. Comes with many accessories in the practical case. In short, it is worth buying it and also buying batteries to change them yourself.

This particular collection has below-average quality. The adjustable tool did not work even once to justify its cost. The wrench was scratched and the size could not be changed. The screwdrivers are not suitable for detailed work. Overall, all the tools feel like toys. Of course, one might argue that the price is low, but that does not mean that someone should throw away their hard-earned money on these few bucks, especially if the job might not get done.
