This tool is good if you are patient and are handy with tools. What you have to be careful about is when you are ready to screw in the handle to push the pin out. You have to make sure that the tool is right on the pin because if you dont, and you think the pin is hard to come out, and you keep screwing in the tool, you can easily strip the plastic threads. You gotta remember it is only a $ 3.00 tool made out of cheap plastic. Ive resized bands on three watches already and it worked fine. In one of my watches the band was 24mm wide and it didn't fit even with the push pin unscrewed all the way back, so I filed off some plastic from the side where the pins come out and it worked. So keep in mind if you have a watch with a band 24mm wide you will have to do that to make it work.
