I am an intermediate player (NTRP 3.5 or 4.0) and I've been making a lot of changes to my grip and form to improve consistency and reduce injuries. Without a reliable practice partner, these changes are not possible, and there is nothing more reliable and consistent than a ball machine.
At this price point, this is a great way to have access to something that is usually available only to somewhat wealthy people. With the lower price comes some cons (no remote, somewhat flimsy material particularly the hopper panels, lack of spin and higher speeds). However, overall, this is a great machine at a great price because it delivers on its basic function - consistently feeding balls to help practice groundstrokes and volleys with very good battery life. I highly recommend to people who can't afford higher end models.
