My husband broke his so I replaced it without him knowing. It came with lots of instructions which were helpful but it would have been nice if there were instructions on how to assemble it. I had to undo the instruction on my own, hoping I don't lose track. I'm very proud of myself considering a lot of tiny propellers and a 22 month old baby bouncing around me. It is durable and made of metal, unlike the original plastic. Be careful with screws. I read reviews before buying. The screwdrivers that come with the kit can tear off the screws themselves. I've used a rubber band for protection whenever I could as long as it's not too small.
