Diadem Premier Pressureless Ball - Case

Fantastic, very high quality, reasonably priced. Absolutely love them.

Okay, so these pressureless balls are excellent, honestly one of the best purchases I've made in recent history. Seriously. I'm teaching my 15 and 13 year olds tennis. I've never used or even heard of a ball like this...airless, no worries about decompression with aging. These things are fantastic. And reasonably priced. As others have said, they absolutely feel and react as well as typical balls that are maybe a week old. Not SUPER springy or tight but really, really good...and for our purposes, they are exactly straight up perfect. The felt is great, they hit great, very high quality, all good. So between this case of balls, and a fantastic, rolling, ball picker-upper we got from NEEWER, and a wheeled ball caddy from PunzQ Sports (on Amazon), we are SET for practicing. We just put in a long, really great practice today, and having tons of balls, a quick way to pick them up, and this caddy...the whole experience was extremely pleasurable. I can't recommend these pressureless balls more highly.

I am satisfied so far with the new Diadem pressure-less tennis balls, they bounce a bit more than the pressure ones and are definitely a little more heavier, so there is some adjustment to do when practicing with the tennis ball machine. I will update my review after some time to evaluate bounce and weight again.

Great longevity with ball machine use

Got these for my ball machine about a month ago. I wanted to get a purpose built ball that could stand up to a ton of ball machine use. So far the balls are holding up really well. I will say, I’m at some altitude (4,500’) and the balls are really energetic and make a great sound.
