I urgently purchased this for my middle school son after he broke his arm. He tried it on once, but it didn't fit because he's slender, and there was a gap, so he didn't use it. I used a similar type when he was in elementary school, and it was very convenient. I will sell it to someone who can use the size. It has only been tried on once, so I am listing it as almost new.
