Tennis ball machine, help please.
I'm a relative beginner and I've been looking into acquiring a ball machine, the only thing stopping me is the price. However I found a spinshot pro machine for relatively cheap. It's a demonstration model and the seller has a good reputation. However, I haven't been able to find any reviews of the product on the internet and was wondering if anyone on here has any experience with the product? What is the quality of the product? Any help is appreciated, thank you.
