Such a lovely idea but sadly not waterproof. Stopped working after one go and when I went to change the battery it had rusted.

I got two for my boys and it’s stuck on. You have to take the battery out to turn off. Water got in the battery area. I was excited for them to be creative.

Thoughts my grandkids would love this. Sadly the on off button was broken and stuck in the on position and the only way to stop it was to remove the battery. Nothing like sad faces on disappointed youngsters to dampen the mood. Don’t waste your money.

we were looking forward to racing two boats but now we can’t because they are having problems right out of the package.

This is JUNK. I bought it for my kids who thought it was great until they built their boat and tried it out. It would not work. We replaced the battery and it worked for about one minute. It is a nice idea, but the quality is terrible. For a company that is supposedly promoting sustainable toys with minimal packaging you are simply adding to the problem with more plastic junk headed to the landfill. Not to mention it is made in China presumably by poorly paid workers.
