Ball Doctor Seals Leaks and Punctures, 1 oz Syringe (Pack of 2)

I bought two, the first one i opened was coagulated and too thick to inject into the ball but the other injector and sealant worked effortlessly. Real simple to use, deflate your ball, inject the product (it injects literally in 1–2 seconds) inflate your ball immediately and bounce and spin the ball around for a minute. Follow the directions but good product to save expensive balls. I used it on a $35 volleyball, worked great

Ordered two of these to fix soccer balls at the school where I work. Inserted the tip into the ball. No matter how hard I pushed, the contents would not come out. Even had some high school students try and they could not get it to come out. Eventually decided to trim some off the tip. Inserted into ball and this time it it came squishing out the top of the valve. Product did not work as expected. Would not order again. Don't know if I will try with the second tube i got, or just throw it away. A waste of money!

This kit warns "won't work on balls with bladders" which is kind of strange, as basically almost all sports balls have bladders. I had an expensive volleyball with a slow leakage, I thought I'd give it a shot, and it worked.The worse thing about this product is the instructions. There is a white cover on the plastic needle, and the instructions don't tell you to pop it off.

It does work (most of the time) but the ball is not the same. Really make sure you bounce the ball after putting it in.

My kids expensive volleyball was no longer holding air, and one of these syringes later, the ball is holding air like a champ and working like it used to with no real discernable increase in weight.I did not expect this product to work as well and as easily as it did.

They were simple enough to use, also you can fix more than one ball with each set. But beware that the item might vacuum and when removed will leak. Definitely I recommend it

The product doesn't work after meticulously following directions and the seller won't refund your money. Essentially they sell a defective product and steal your money.

We saw the Harlem Globetrotters and had a great time. They sell two basketballs - regular size and small (like a size 3 soccer ball) We got our daughter one of the smaller balls. It developed a noticeable hole, ~ 1/16". I ordered this and it worked! just open, insert, plunge the fluid and bounce it a bit... and let it dry overnight. The sealant bubbled very lightly through the hole, sealing it closed overnight, just as advertised.And she's quite happy playing with the ball again! Thanks, Unique Sports!
