Unique Sports Ball Doctor (Quart), BD-2

Great product... just follow the directions and it works well. Using the quart size bottle of Ball Doctor, I've repaired one volleyball and seven basketballs (old one, most newer... some leather, most streetball rubber), and all of them hold air a month later. One bball took two attempts... probably my own fault because I didn't use enough product in the first go-round due to loading the syringe wrong (see tips below).The bad reviews on this stuff are probably from people who can't follow directions or a few who got dried out single-use packs (quart size is cheap, repairs about 30 balls, and stays fresh from a tight sealed bottle). There is just no way I've repaired a half dozen of my balls and some basketballs for friends on the first try all by luck yet other people have such a tough time. Take your time, and you will be pleased....A FEW TIPS: the product label has limited directions. They are good directions, just limited. Here is what worked for me: the same directions with a few more small additions:1) Have the ball a bit flat to start (zero PSI). If it has pressure, it might shoot out some of the goop or the whole syringe plunger when you insert your syringe.2) Shake the Ball Doctor bottle WELL, and it will look thick like tan pudding with bits of rope fiber in it.3) Take the syringe cap off by pulling straight (don't need to twist/screw it). ***IMPORTANT: To fill the syringe, you have to take the plunger out and slowly dump some of the goop into the red syringe from its top. One ounce is for balls (soccer, bball, vball, etc), and that's roughly a half full syringe. The label instructions are not clear on this, but it is very key to the repair to have enough. Do NOT try to draw up the goop product through the syringe tip like a medicine or typical liquids syringe... that doesn't work due to thicnkess, and you will only get a few drops (yet won't know that since you can't see through the syringe). Again, remove the plunger and dump the goop in the syringe top... don't worry, it is too thick to leak out bottom tip.4) Get the syringe tip wet with water or saliva or whatever and push straight into the ball nozzle. Have your thumb on the syringe plunger at this time in case it gets pushed up (shouldn't if you have zero PSI ball).5) Once the syringe is in, push the plunger down and you will hear a splat sound of the goop going into the ball. Pull the plunger up an inch and push down a couple more times to get it all inside. Take the syringe out very carefully (quart bottle will last for roughly 30 repairs, but you're screwed if you break the one syringe).6) Pump the ball with air to the high end of its PSI rating on the ball (usually 9 for bball or 5 for soccer or vballs), then bounce many times, spin, bounce more, spin more, etc.If it holds air after a day or two, it worked. If not, you can try again, but the weight of more and more of the Ball Doctor goop would probably eventually mess up the ball. Good luck, hope this helps... fantastic product and saves a ton of money if used correctly.

This product is not useful, I have 4 volleyball balls and used this product per direction in all four but non of them get fixed and still has air leakage. I used the product 4 consecutive times in of the ball and couldn't fix it and eventually the weight of ball got heavier, now the ball can't be used it anymore.

As other reviews state, it is challenging to use and gets clogged easily with the fibers in the solution. But it does work. I have fixed 5 well loved balls with this and the balls are still holding air days later.

it adds quite a bit of weight to the balls. I was able to repair 3 different balls for my 5 year old son: the Spalding NBA All Conference Indoor/Outdoor Basketball (27.5 inch), the Adidas 2011 Glider Soccer Ball (size 3) and a Franklin Sports Grip-Tech Mini Football.We have a bunch of Agave plants and my son managed to get each of these balls into the plants. Well after ripping out the Agave plants, I ordered the Ball Doctor from Amazon. I opted for the free shipping so it took 8 days to arrive. It was easy to use and worked right away. So for its use and functionality I would give this product at least 4 stars. So far it's been 2 weeks and it still holds air. Mind you that the agave plants have pretty big thorns - at least the size of a small nail. So that was impressive.However, be aware that whatever amount you add to the ball that will be added to the weight of the ball (I docked a star for this issue). Maybe it wouldn't be an issue for others but for my 5 year old it was significantly heavier than his other youth sized basketball. It might be good for his weight training and building up muscles but at that age they only want the easier/lighter balls. I will admit though that the extra weight to mini-football is actually nice since it was too light to begin with.I will use this product again but only when the weight is not an issue. But then again what else are going to do with a flat ball. Toss it in the garbage or make it work.

This stuff is amazing. Had no thoughts it would actually work, but it does. Used it on about 30 balls for a school; basketballs, volleyballs, and small play balls for the younger kids. Pitched two of the bald out because they were being saving and that’s ok. Understand that this won’t patch a torn or totally worn out or rotten ball, and that isn’t the intent. If they are in fair shape this should work. Even on the fairly poor balls I would give it a try. Balls are expensive, this in relation, is very inexpensive.

Comes with one syringe. For that amount of product should come for more than

My kid loves to play ball in front of the house but i have a cactus garden joshua tree and all and the slightest bump from any ball makes the ball flat in an instant! Got a quart of this ball doctor and repaired all the balls fast. Tiny cactus pinholes are no match for this stuff i was a bit skeptical but it works and i almost had to give up some of my plants to satisfy the family so that saved my garden. Now if they dont like em they can move out!: )

The syringe is of poor quality and totally ineffective for injecting glue in a ball.
