I buy a Beta titanium frame for my child -4 year old, the retailer said that this frame is unbreakable, even if I don't believe it. Purchased it since the price is too cheap. try it, and hope it is well. I will feedback.

in my opinion, and many times use experience, th beta titanium frame is just the temples are unbreakable, not the whole frame, most legs are memory metal or titanium. So.... cheap is common thing.
