Excellent design and durability. Negative: After a while it comes off its position - it needs to be repositioned and tightened properly on the strap

Very high quality. However, it does not have a good fit at all, as it pops up and comes off as you adjust it. The round button at the back to tighten and loosen the helmet is not functioning correctly and is almost hidden, and it cannot be reached except by a child's hand, but a 2-year-old child cannot do such a thing... Finally, the four yellow inner elastic "things" that hold the cushions catch the children's hair, and either you pull out hairs or the helmet does not come off.
