Very happy with this belt! It fits my 4 year old well and the buckle is easy enough for him to operate on his own. Update: Changed from 5 stars to 4 because the seller sent a TON of emails asking for feedback! I've already gone through this nonsense and they STILL bother me! A message or two is fine, but I'm pretty sure the last one was the 4th letter! Serious overkill and I'll probably avoid this seller in the future because of that!
