I bought this product under the pretence that it was for my son but as he is only 5 months old this was fooling nobody!
My one worry when buying this product was due to the fact it was a moveable unit, whether it would stand up to 30+ males thrashing the ball around without collapsing or breaking.
I'm please to say that once we filled the base with a couple of bricks and a bag of sand, then watered the sand, it was very stable. I would only recommend using water if this is purely for children.
It was easy to assemble and is still going strong even after a house party at the weekend where it was in constant use. Due to the heavy nature of the bats it's also a surprisingly good and fun workout.
