With in a semester my son was already needing a new one, I thought that maybe it was poor quality until I picked him up at lunch when they had it outside. Him and his friends were throwing them kicking them slinging them. He even throws it down the concrete steps as he was walking towards me I payed attention the rest of the day how he sat on it, stood on it, used it as a plate, spill drinks on it. Slammed it down threw it in his room drug it took and from the car. So a half of a semester of that kind of torture I think it did very very amazing.
