My daughter, 14, is a martial arts machine with great form and power. My son, 10, is floppy and all over the place. They both love them, using them with their kicks. It mostly confirms my daughter's awesomeness, which is nice.
The real benefit is it has given my son instant, no BS feedback on his own form, which is great since he's not the best listener. He's figuring out that a kiai has a real purpose, that proper form and execution matter, that accuracy matters, and when you do it right it feels easy.
Feels and sounds like a real board when it breaks, slots right back together. So far not wearing out.
Could have gotten an easier one for his spinning back kick. I think I can simulate an easier one by not sliding the two halves fully together.
