Bought this originally for my son (when it was still under Itech name) when he was 10 or 11. He thought it was suffocating and went back to the cage after just one training. I think the reason was he was kind of in-between the sizes; this being too small and the senior version still too heavy.
My daughter took this (she was 7 at that time) and fell it love with it. Still uses it after 1.5 years but I am buying now a new one as it has scratched little bit too much.
