The tool is super easy to use. I did glance at the 3 or 4 lines of instructions, but that was not really necessary. I had never before even seen any tool like this but since it was so intuitive, I managed to remove 2 links from my wife's new Citizen Eco Drive watch with metal band within 1 minute. In less that 2 minutes, the watch band had been resized and ready to go. At the mall, the watch repair shop had asked for $8 to do the work, Sears had asked for $10 and JCP had quoted $12 for the resizing. I got the tool (with tax) for $3.25 and now I have it to use many more times if needed. What a deal!
