Old enough to remember "Japanese Junk" ?...welcome to Chinese Junk. This gem comes with NO INSTRUCTIONS. The buyer must consult the internet or elsewhere to find out how to use this plastic piece of junk. The tool is made of CHEAP PLASTIC which makes the moving parts unprecise to use. Aligning the tool with the watch's link pins was a nightmare. Did I mention that the Chinese Manufacturer didn't even include a one sentence instructional guide?  Can someone tell me what the METAL SERRATED KNOB is for???? I'll be honest and say that after checking out Youtube I was able to effectively readjust ONE notch on the 3 notch watch bracelet band's clasp to fit a little snugger but was afraid to try my hand at removing 1 or more links to complete the job. In the end I had to take my watch to a jeweler and paid $6.00. How much longer must we endure the Chinese Invasion of cheap, substandard, crap??? Buy American!
