Easy to use, worked o get some old watches open to test with new batteries. Worth buying if you have old watches.

Didn't have no issues , worked good ..

i chose this one because it had the best reviews. at first, i was ready to return it insofar as it felt loose, rather flimsy on the adjustment screw, and i couldn't even nudge the back of watch. i have the standard notches on the back of 2 Seikos. So, i wanted to give it another chance and think thru a method. what i recognized was where i had the batteries last replaced. one was done at a cheap, mall watch place on the other side of the planet, not mentioning a country. one is well advised to know when dealing with watches and other items to go to learned and certified watchmakers. on one of the Seikos it was as tight as ice. You do not want to scratch your watch back and you need to protect your fingers and hand. i took this one watch and placed it crystal down on the bed, stood over it directly, adjusted and placed the tool, and applied A Lot Of Weight and proceeded to turn to open ... watch those fingers! That did the trick. The tool worked fine, and it was the ineptness of the one who tightened my watch the last time i had a battery replacement. the other Seiko was tight as well, and i needed to do the same on standing directly over it, but it was easier to open, and i noted that this one was done by a watchmaker of many years, in a foreign land. the point here is to note that when you have these items done, is to go to a professional to begin with. The tool worked just fine. It appeared to have the best product reviews and lived to that standard.

This device did the job for me, but not too easily. A lot of your success with this tool will depend upon how tightly the back case was screwed on by the last person that replaced the battery (or by the factory). In my case the back of my Fossil watch was on very tight, and it did not yield easily. It was hard for my hands to apply pressure and get the desired leverage to make this work. At one point I was about to give up. The positive reviews told me that this could work and often did work, but in the case of this watch, it was not working. Finally I prayed and got the idea of attaching a small pair of vice-grip pliers to it and after a few tries this gave me the leverage to loosen the back. When it first began to give way and turn, I was elated. This device should work for most people and most watches, but not all. I think the type that has three prongs and a longer handle would be significantly better and would handle even the difficult cases. But I plan to tighten this somewhat loosely once I get the replacement battery, so that next time it will not be so much of a pain.

Excellent tool. Great addition to my kit.

Excellent tool for very good price!

Perfect. Very easy to use

The posts were too big for the notches on a child sized watch and would not fit. Probably fine for an adult sized watch but not smaller. Function and form solid. Like I said cant fault the tool as it was made for adult watches.
