I have a U8 team that I use these for they work great the adjustable heights come in handy because if you run a circuit like I do my training after 20mins or so of running and doing multiple drills and jumping these the kids start losing jumping power I just convert them to the lower height and they can continue jumping them instead of just going around them when too tired. The bag is great hasn't ripped looks and feels very durable and it's actually a little bigger than what's needed width wise as in space in the actual width of the space inside the bag. Which is good sometimes I throw random stuff in there water bottles or goalie gloves whatever when I'm in a hurry. I'd recommend them to any U10 and under coach I say this because they aren't the highest hurdles for 12+ I'd go with a bigger hurdle in that case, but for what i need them for they'll be good for another 2 years not bad for 6 hurdles that are adjustable and come with a bag! O and hurdles are durable first day I got them one of the Janitors at the school we were practicing at was oblivious to the hurdles and ran them over with his golf cart they stayed intact and just like new minus the scuff mark from the tire lol!
