Good build quality. However, it Doesn’t work at all on my pavers. Very difficult to move a 16’ trailer with 2000 lb load up a 1% grade. I’m a big guy too. It also has a tendency to tip mostly because the wheels getting caught on the paver edges.
It is good quality nicely made but it’s not any easier then any other trailer mover if your going to spend this much you might as well get a trailer mover with a motor.
