Very much an essential piece of kit now, saves enormous amounts of back breaking work.
I've a 2 ton box trailer loaded with a race car, tools, spares, wheels that was a endless head and back ache to empty and then manoeuvre.
Setup took some time as fitting the clamp but adding some backing plate supports to the Trailer chassis too took longer than planned.
The clamp could certainly do with being heavier for bigger trailers, in my case I don't need to use the jockey wheel extended so I gain as much support as is possible in its shortest state.
Generally though the clamp is working fine for me although I can see there is play/tension/stress on the clamp when the trailer gets stuck against a curb.
Operation is perfect and controlled on good surfaces and as the product details say it won't work well on loose ground or grass.
In my case I have this issue which I can get around with a big bit of old heavy duty carpet.
Last issue is that the handle isn't long enough to extend past my hitch even though I've fitted the clamp as close to the hitch as possible on the chassis.
Thankfully the wires from the handle to the motor are plenty long that I could add a 20cm extension between the handle and motor to sort clearance.
Basically its perfect for what I need, just took a bit more setup than expected.
