Had one, a clone for $250 or so. Worked fine.
1. I actually have an insert into the hitch of the hauler that uses ~19mm bolt to hold it tight to the hitch. This stops the wiggles.
2. It's still a haul and a half up on the ramp onto the hauler itself. You are going to be lower than the bike and you're going to want to get your straps squared away before you get it up there especially if you're working alone.
3. Getting it up is easier than getting it back down. Plan accordingly as you have a motor to help go up the ramp, but if you are parked weird (slightly tilted) your going to not only be fighting the balance but trying to force it backwards.
Two straps around the wheels, straps on the handlebars (total of 4 for the front, two on each side) a pair for the pegs/frame and I liked using a ratcheting strap at the center to help pull everything down tight.
Hundreds of miles later... prefer riding the F800 and hauling the KTM.
