It works as expected. I dropped it 2 starts because after you put in the code and press the release button, its still a bit hard to pull out of the lock. I would expect it to pull out freely. I got this for my young son, and its a bit hard for him to use since you have to pull the strap hard while also holding the release button. This makes him not really want to use it when he rides down to the part. I does work though.
