Fixing the size of ur band at home is the way to go! Buying this costs the same as having it done at the shop. All you do is put the watch band on the leverable platform (push down to level the pin with the watch band pin hole). Then rotate the dial so that the pin goes into the pinhole and knock out the pin in the watch band. Easy! Comes with extra pins just in case u break them. Just have good eye sight on the hole and pin and u wont need them.
