These tubes are easy to use and effective, ahemm, but, don't count on them to last forever. The shoulder strap will fall off and with a significant amount of use, the bottom ring will will no longer keep the balls from falling out. For light or occasional use, these are excellent. 3 stars

It's quite simple and it works well. I think I would want a longer one to hold more balls. 4 stars

We ordered 2 of these tubes at the beginning of the summer - we've been using them several times per week and they work great! They've held up just fine and so far we've had no problems! 5 stars
