This is only my second time using it and I didn't even twist it by force and the handle broke. It's a great design and handle assembly, but the 2 rings that hold the handle together for tightening are VERY VERY flimsy and flimsy. Have your kids tighten them so they don't break IMHO!. I'm trying to find a website to see if it replaces them, but I have a pretty good feeling it won't! it is up to your tires to leave the campsite. The lock broke after the first use.
