Micro X balls have a consistent bounce making them great for ball machines.
I use the balls for training with my daughter and in Spinfire 2 ball machine. I am very happy with the performance of the balls. They feel very similar to regular pressurized balls and not hard like many other pressureless balls.
I've been using these balls for several weeks. They play great; not at all heavy. Small differences -- they perhaps sound a little louder when struck, I think they pick up better on half-volleys than normal balls. Of course the real differences -- they use far less plastic than normal balls that come in a tube and they apparently last forever. I'm looking forward to seeing how long that is. Overall, they are bound to be more economical.
6 months and they're like I bought them yesterday.
Second time buying these balls. First batch lasted almost 3 years with heavy ball machine practice use. They are slightly heavier than pressure balls, but you barely notice and they last years. Towards the end of the 3 years, I started popping some of them while serving - so just purchased another 2 bags for the next 3 years. I am 5.5+ player and played D1 tennis in college, so I hit harder than most recreational players.
Well made; true bounce; heavy but expected; perfect for ball machine
