It's fine

For the job it's intended for, it's fine. You have to be vvvveeery careful through paveways because your gear could end up in some dog's poop hole while you're not looking. So, use hook/rubber bands to hold everything on.

Not very stable but still, very helpful for carrying gear before and after a gig.

Don't try to move furniture! Not a good idea. (I tried and failed, so now you know)
