Sleeps like a pro. Well I can hold out for about 30 seconds and still make it come back. If you use an unresponsive bearing it will last longer, but it requires a fixing trick to get it back. This is normal, see instructions on YouTube. I still haven't mastered it. Be careful with this heavy yo-yo! If you expect him to fall asleep and he doesn't, he may come back heavy and painful. Just be prepared in case the dream fails. It's solid, strong, and heavy, which helps it spin longer. The strings are easy to swap out so each of my sons has their own length.
