Just had my first chance to test out my proton with a full case of (triniti) balls today and it was quite disappointing. I was on court for about an hour and a half and it got stuck like 10 times. Spent most of my time figuring out how to get the ball out and wasnt able to finish up a single round of balls. In addition to that it also 'stopped' for no clear reason for about 15 times (with plenty of balls remaining. Starts again fine when I press start on my phone). Not sure if it's just my unit. Sent an email to Novia and let's see what happens.
