Tennis Scorekeeper and Vibration Dampener

It is a little tough to get on, but after that it has been a lifesaver for me. I can concentrate on the match and not repeating the score in my head over and over! I just ordered more for my teammates I just wish it was on prime bc $13 is too much for shipping for an item weighing nothing. Stars lost for that reason only

I love this simple scoring device. You don't have to wear anything on your wrist and it doesn't need batteries. I'm surprised to see negative reviews. Yes it is a little difficult to get installed, but mine has never popped out. It is not difficult to turn and once set the score never changes setting on its own. After a couple of years use, one of the ridges for turning broke off. I will buy a replacement. You do have to make it a habit to record the outcome after every point. I find it is an ideal ritual to set the score and focus on my racquet for a moment after each point.

Still going strong , use it now and then

So helpful to keep score while playing tennis.

I have had several of these--somehow I keep giving them away. The older versions "clicked" into place a little more easily. This one seems just a little more prone to be in between points. That being said, I definitely recommend this product.

Love it, very handy in long matches when rebuilding points from memory gets hard. Would prefer the nubs to turn it be more durable, but overall a small and handy little tool. It won't last forever, will wear out, so I keep a supply in my bag.

Nice little gadget. I added marks on the outer wheel with a sharpie to find the score numbers faster. My first one lasted about 2 weeks (the plastic ridges to change the score tore off) playing 4 hours twice a week). Worth the price

It's a good idea but too small. i should've checked the size (didn't think when i saw the picture), it's a tad bigger than a nickel. as i need glasses for reading, i can't see the score. so now, i have to find someone to play with who has good eyes or that can remember the score.
