I teach tennis at my house. My students leave their old used balls. I have not purchased tennis balls since I bought 2 units, each one holds 60 balls. I bought the units in May 2021. The unit works so well that I have an emotional problem getting rid of the tennis balls that are pretty much bald. I finally got rid of around 300 balls that were perfectly good in terms of bounce. It took me 3 years to finally do this. I still have balls that have lots of felt waiting for a treatment. This is the best tennis investment I have ever made. Balls are ridiculously expensive now, so you must have this product. It will save you gobs of money, and it has no parts that break.
A really good company to deal with, and the order / shipping process was both easy and quick. Regarding the “pressure refresher” performance. - I have not used it long enough to provide useful information .
I purchased the pressure refresher shortly after getting my first personal ball machine. With a ball machine there is three options from what I have seen, spend tons of money on new balls, use pressureless balls, or re-pressurize your balls. I tried them each in that order. The amount of waste and money on the new balls was unstainable, the pressurless balls DO NOT feel like normal tennis balls, but the pressure refresher is a total winner. I have been re-pressurizing balls for three weeks now and it was a bit of a learning curve figuring out how long to pressurize them for. I started with a batch of very very old balls and decided to leave them in the refresher for 5 days. They came out bouncing like moon balls and sounded like a basketball when they bounced. However when I put them in the ball machine at full speed / full topspin it was one of the best workouts I had had with a ball machine. However, this is not ideal for play. Now regardless of how dead the balls are I never leave them in for more than 2.5 days. They work great for the ball machine or doing drop and hit drills. Now I only have to get rid of balls when they lose all their fuzz. On top of this Dave was a great point of contact when going through the decision to buy this. I am trying to convince my tennis club to buy these so we stop wasting so many balls there now. Any tennis player / coach that spends more than a couple days a week on court need this.
Got the 60 ball pressurizer. Works like a charm. I use a ball machine, and after several weeks of rain and no use, the 60 balls would not be useable after maybe one or two uses. Now...no problem. I just stash them in the pressurizer, pump it up, and they are fresh for the next use after a stint in the pressurizer. Perfect...and easy to use as well.
My tennis ball refresher works great. I haven’t tried to pressurize any old balls yet. I have used to maintain pressure on new balls. So far it seems to be working excellent. I pressurize it to 20psi, and the container never dropped pressure for an entire week. Balls seem just like new. We will know for sure with a couple more weeks on how long the balls will remain pressurized.
I took 60 old padel balls that were stashed in my garage over the last 18 months and set them to recharge. I have only used the first 6 so far and am thrilled with the recovery.
We play once or twice a week but like to have a lot of balls to use so we don't have to keep stopping to pick them up. The pressure refresher has restored the bounce in them and keeps them good until the surface wears out. We estimate it will pay for itself in about a year. For use its a good ROI.
Works well!! Different balls will require you to repressurize at different PSI. For example, I was able to bring some new "Costco Penns" back to life. For those that don't know, new balls still in the can, go flat over time. Often times the balls you buy at Costco are flat when you open them. These required very high pressure. I had them at 35 PSI for a few weeks, then 40 PSI, and finally 45 PSI. They bounce like new balls should. Other balls that were bouncing fine out of the can won't require that much pressure. Probably closer to 30 PSI. I now grab any ball I see on the court that people leave and put them into my Pressure Refresher so I always have a supply of good "practice balls". Thanks.
Fast shipment, just like Amazon prime, it only took 2 days to arrive. I am very happy with the item.
After 10 days in the refresher, we’re getting tons of bounce from our two month old, foremerly flat tennis balls! Could not be happier. We went out to hit today with a hopper full of re-pressurized balls and were blown away. My wife even called her coach over from the next court so he could give’em a test. Great concept, excellent execution. I’m impressed.
I bought two of them. Fantastic product. Holds pressure and doesn't leak. I can fill it easily and it absolutely keeps my tennis balls fresh. I teach tennis. This will help my students hit with new feeling bounce every lesson and will save me alot on buying new balls every two weeks.
Works great. There is a slight anomaly with the Schrader valves. They are on a soft base and the center moves around the inside of the valve making a solid connection a bit tricky. Also, if I put the valve cap on one of the kegs (I bought 2), it will depress the valve and thereby emptying the keg of the co2 gas, so I just keep the valve cap off of that one. Other than that, my first two repressurzings went well, repressuizing 120 balls in 3 days. Working my second 2 kegs with another 2 more to go after that, 370 balls in all.
I ordered two kegs. They arrived on time and in perfect working order. They had replaced the rubber o-ring. These kegs will be used for keeping tennis balls pressurized. Seems like this will work for decades. I may buy a few more as XMas presents for friends that are crazy about tennis.
The product is so great and innovative! It is exciting to me and my team members. It seems developed by your string mind set for sustainability. I hope this product will be known better and more widely in tennis space and private networks. It must gain a lot of good reputation by many customers. I hope your great success in all businesses! Thanks a lot for your prompt and kind response!
We had heard about the Pressure Refresher, but this was the 1st time we were using it. Definitely exceeded our expectations for our year old tennis balls. After a week at 32# in CO2 the balls bounced just as much as my brand new ones. Definitely telling all my fellow tennis parents about this product. Tremendous!
We can go through a lot of tennis balls, particularly since we use a Slinger Bag. We were looking for a method of extending the life of the tennis balls and found the Pressure Refresher. We bought the Pressure Refresher keg and a 10 pound CO2 bottle that we fill at a welding supply store. The system works great. Used balls are restored to near-original condition--I can't tell the difference-- after three days in the keg under 40 lbs of pressure with CO2, and they are maintained by keeping them in the keg under 14-16 lbs of pressure with CO2. Rather than going through hundreds of tennis balls per year, we are able to get used balls from our club that are destined for recycling or the trash, refresh them, and play on. We have told our tennis-playing friends about it and hope to convince our club that they should consider this option.
Thrilled to have purchased this for our Tennis group. Thanks, we will definitely be back in the future!
