The product works as intended... good tool to have on hand for whenever any of your watches' batteries may die.
I've ordered this and it took a little while to figure it out since the watch has never been opened before. I felt it's wiser using the yellow holder to secure the watch. Since I have 2 watches this is a must gadget!

Despite loosening up a little while using it, it did the job just as you would expect, and it did not leave any scratched, so that's a plus.
