If you haven’t already tried one of these, they are easily the best device for ball picking despite of its size. I never really like any ball tubes as I find them too slow and not quite practical but these rollers are simply so great. Of course, the downside is the bulkiness, but it does its job perfectly. Give it a try if you haven’t already yet, saves you plenty of effort and practice times. Each full load is more than 3 times a tube’s capacity too. tennispractice
