Worked great on a stubborn watch back. I saw a review video by a watch repair person that went over the various types of screw case back opening tools. Surprisingly these ball types came out near the top. What's good about these is there is no chance of scratching the case. This tool is for screw back cases only. Snap backs need a different type of wedge tool. When coupled with a case holding vise opening a screw back case is rather easy. It requires some effort and patience. Make sure the ball and case back are clean. No choice of color but I got blue. Read more
It worked amazingly, I was surprised how easily unscrewed the back of my both watches. Read more

I wasn't sure what to expect when I ordered this ball, so I had no preconceived notions. I got the blue one, which I was hoping for, as the yellow would show dirt too easily. The rubber the ball is made of is more a plastic than a rubber, and I was skeptical it would grip the case backs. But it did what it was supposed to do, although it was too big to fit inside ladies watches bracelets, so you have to pop a link pin to remove one end of the bracelet to be able to use this ball on those. In terms of value for the money.........it's a small plastic ball, so couldn't cost very much to make.......so to me there's too much profit involved for me to rate it a good value for the money. You could probably find one of those free stress balls everyone has in their desk at work that would do the same job, but I digress. Overall it worked........at least on watches with a big enough bracelet to allow the ball to fit in the ID.......so I'm satisfied. Oh, it also comes with an inflation pin and mine was properly inflated. ;O) Read more
I picked up this friction ball to help open the case back on one of my watches, but it didn’t end up working for my particular model. To be fair, it might not have been the right use case—the case back was probably too tight for a friction tool. That said, the ball feels well-made and grippy, so I can see it working fine on watches with easier-to-remove backs. Bottom line: Didn’t work for my watch, but seems like it could be useful depending on the watch and how tight the case is. Read more
The sticky ball watch back removal works quite well .. The one i received is yellow ( not my first choice of colors but who cares it's a ball ) came prefilled in it's own cardboard box , i was hesitant to purchase because of all the choices of sticky balls on amazon with mixed reviews , This one had mostly good reviews so i decided to try it anyways and for 7.99 at the time of purchase i couldn't be happier , Worked great on the first two watches that i tried it on so it's already paid for itself in my eyes . Both watches were a little hard to get open at first but within seconds they both opened right up , the ball has great gripping power and no slippage , pre inflated so there was no messing with guessing on how much air needed to be added before use . It does come with a filling needed which i put away for future use if needed but i am quite happy and impressed with it as is right out of the box ., i would def. buy again if i needed to replace . This is the one to get if you are like me and having a hard time deciding between the affordable ones and the marked up name brands that can be priced upwards of $15.00-$20.00 . This one worked perfectly at the 7.99 price so far . Hope to get many uses and years out of this sticky ball watch back removal tool , 5 stars ***** Read more
The ball arrived in a plain little box with two inflation needles and no instructions. Knowing the ideal inflation pressure would have been handy, although the small size of the ball makes hitting a precise number difficult. Even quickly yanking the needle out causes a little loss of air. The ball was inflated when it arrive, albeit a little squishy. After a few unsuccessful attempts to open several watches, I added some air to firm it up somewhat. On one watch, I managed to get the back cover to rotate a tiny bit. But I couldn't get it to keep going. The problem is that this friction ball relies on you pressing it very firmly against the back of the watch and rotating. If you don't have enough pressure, the ball slips and doesn't move the cover. I found myself really exerting a lot of force to prevent slippage. Even then, the cover didn't rotate. I gave up and ordered a proper kit with a case wrench and a bunch of other watch tools. My guess is that one could open some cases with this ball, but far from all. Inflating the ball to as firm a pressure as I could manage seemed to help its contact with the watch case. Read more
Does what it is supposed to do and opened the 50-year-old Zenith with minimal effort, zero damage and no need for other tools. Read more
