Arrived on time in a well beat up box. Contents OK. Quick & easy to assemble. Nice over center locking of the axles to cart. Fold the sides up and lock them in with a nicely made pin system. Aired up tires & it was ready. Installed the hitch connection on to my bikes axle using the bikes nut. The only problem with this connection is that it rotates downwards as the trailer bumps along. I cut a short hacksaw cut and used a punch to drive a nub over so that the nub would ride against the bike frame and stop the hitch pin from rotating. So far it seems to be working fine. My first thought was that it would limit how tightly I could turn, but no issues at all. It bounces over rough streets because the only "suspension" is the tires. The tires are round in cross section so they provide some cushioning. The rated load of 275# seems optimistic and I'm not sure I would like to tow that much. It has done fine with about 80#s. Wheels & tow bar can be removed really easily and the sides folded down flat for winter storage. The heavy spring tow bar connection seems like a very good solution to all the motions needed.
