I use these with a team of 13 little leaguers that are 7-8 years old. We use these before every game and every practice and the boys run around them 4 times per event. So, that's about 50 touches per event. We've had about 30 practices and games so that's about 1500 touches so far. They're getting real dirty but they aren't breaking and I'm very pleased with them. They're quite heavy but that's necessary to make them last. I am very happy with them. They make a great warm-up station. Have your kids run around them and practice their base rounding technique, checking for signs from the 3B coach as they run, etc... I like being able to set them at a shorter distance so we don't tire the kids. We're just warming up. After two round trips we do a full round trip doing shuffle steps and then we finish w/ a "4 step combo" which is a run to first, shuffle to 2B, back pedal to 3B and criss-cross to home. It is far better than running out and touching the outfield fence.
