It looks like an identical design to an old Halfords one we had, but with different wheels - I think it's a generic design. The frame and hood are exactly the same. I'd say they are they are adequate. You definitely don't want to take liberties with your kids in it, compared to say a Croozer trailer, which feels like you could flip and the kids would still come out unharmed. It does feel pretty flimsy. We've since got one of the Chariot trailers with suspension for when we need to go faster than the cargotrike wants to.
