Very nice tool for the price.  While I am sure the "pro's" use something that costs 10 times this, don't let that stop you from buying this one. It works, and it appears to be of high quality. I purchased this because I have more than a few Swiss Army Watches, and I hate taking them in for batteries..some places won't touch them. Not wanting to spend a fortune to find out I could not open the backs myself, I invested in this tool. Within half an hour of getting this in the mail (free super saver shipping) I had opened all 3 watches that need a battery, without a scratch to the back of my beloved S.A. watches. Yes I am happy with this purchase..whenever I can do something myself instead of paying too much to someone else to do it..I get happy. In my opinion, a good quality tool.
