Very poor construction. The wheels keep coming off. It's not a matter of whether it's worth the money, it's not worth it at all if you have to tighten the back wheels every 2 hours. And it should be made clear that the construction has nothing to do with BWM. Just a simple sticker.

Good construction and good size. It seems to withstand the weight, but time will tell. I hope the service is not as expensive as BMW's.

Update: Well, we barely used it 2 or 3 times and on the rear axle, one wheel gets stuck because the screw tightens with movement and then it doesn't rotate since the wheel doesn't turn. I don't know what happened, but it seems like the axle that holds the screw and wheel broke.
