Negative Positive
Title: Not worth the effort or cost
Review: I tried this product on 5 watches but could only open one. The product is actually well made but doesnt work on most watches. One huge problem is that everytime the blade slips off the back of the watch cover it hits your thumb. One blood thumb which I hit numerous times and the fact that it did not open most types (all of my watches were different backs) makes me rate this product poorly.
