Purchased on Dec 18 as a 2020 Christmas gift for my 9-year old son. He was excited and tested after assembled. Then snow came, the unit was in placed my storage until late March.

When it happened, my son was falling off the unit and got a scratch on his leg, bleeding (so, UNSAFE!).Note, given their 90-day warranteSee full review
