Featuring patented technology, the Tretorn Micro-X Pressureless Bag of 72 tennis balls offer high performance and improved playability. These pressureless tennis balls are powered by 700 million air-filled micro cells that maintain bounce over time. Its highly visible flex-felt offers strong core dynamics and durability. Due to its construction, the Tretorn Micro X pressureless ball is well suited for colder climates, at high altitudes, and all court surfaces--even lower bouncing surfaces. Recognized worldwide as the superior pressureless tennis ball, the Tretorn Micro-X is perfect for practice and tennis ball machines!
I bought these years ago for my ball machine and they were fine. They eventually wore out and I tried a cheaper alternative, but those balls were junk from the start. I bought these again and would only recommend these from now on.
Bought for use in my Proton ball machine, previously used Gamma balls from Amazon but they gave off a ton of felt fluff and degraded fairly quickly. These Tretorn balls are holding up much better - less fluff and more consistent bounce.
I had not used Tretorn nor pressurlessm balls since I was a kid but was so pleased with the initial bag that I bought another. They adapted very quickly to our ball machine and had a quality bounce and spin on our court. Have kept their cover and shape well after several weeks steady use. When needed, I would not hesitate to replace them with another bag.
These balls are great. I'm on my 3rd bag. I originally bought them to avoid throwing away a plastic can every day. They bounce well and last a LONG time. My doubles partners are fine with them. They cost a little more, but end up saving a lot of money. Eventually the covers fall apart-- after probably 20 uses of hard hitting .
I like the Tretorn Pro Lite tennis balls best. The Tretorn Micro-X tennis balls felt very heavy when hitting [I sold them cheap to a friend]. 15+ years ago the Tretorn Pro Lite tennis balls were made with a different rubber that made the tennis ball bounce more as the ball got older [I liked those tennis balls best]. The newer version Tretorn Pro Lite tennis balls bounce less as they get older and I do not like that. I own both the 15+ year old Tretorn Pro Lite tennis balls and the newer version Tretorn Pro Lite tennis balls. I wish they would make the Tretorn Pro Lite tennis balls with the same rubber they made 15+ years ago; I'd rather have the balls bounce more as they get older versus bouncing less as they get older.
