Internal oscillation: the most advantage of siboasi tennis shooting machines

see comments below from one of our clients about it :

I tested the machine a few times. It’s been already about 6+ hs of use with the first battery charge, and still 40% left!. I’m very pleased with the operation and robustness of the machine. The fact that is has internal oscillation makes it very precise and it keeps the precision from the 1st till the last ball, which I know that other well known brands with external oscillation cannot. I’m using 80 standard pressurized balls for about 1 month already, and so far so good! Overall a great product, w/outstanding sales support.
