Again Chinese made....and AGAIN NO INSTRUCTIONS ..or ANYTHING!!! I had to figure this thing out myself. Am I a freakin Jeweler??? I've used it once to remove the back of one of my watches for battery replacement and SCRATCHED the BACK BIGTIME because ..NO INSTRUCTIONS!!! The tool seems substantial enough but looks like Chinese RUST is just waiting to happen. I guess that's why everything in the box is coated with an oily film. I gave this thing 2 stars and only because I was able to make it work even if I ended up ruining the watch back. Do yourself a favor and shop around for another brand where they actually care about their customers..perhaps Made In America.
