Senior Tennis Player
I'm a senior tennis player and I live a half block from the courts. Carrying a ball hopper was a lot of work for me and that's why I bought this model with wheels. It worked well for about one season, then the wheels started coming apart. I used epoxy and repaired them several times but the wheels keep falling apart. So, if you are thinking of buying this unit just because it has wheels--expect some problems. Otherwise, the ball hopper works very well.
