This is a great little item for sizing watch bands!! I had never tried doing that before. Just received a new watch, and the tool, today. The tool was very easy to use. The hardest part was lining up the pin with the watch band (all you need is good eyes and good lighting) - but once you do that, you just hold down the band with a finger and turn the 'screw' of the tool, and it pops the pin right out. Very slick!! I removed 3 links and had the watch fitting perfectly in about 15 minutes. Saved a trip to a jewelry store and needlessly paying them to do a job that I can now do myself. Great little tool at a great price!!
