I am loving it so far, about 500 miles on it. Like I said, silky smooth is the best way to describe it. Low to the ground, so getting the yak on/off is a piece of cake.
I own the larger HF trailer too - mostly for hauling 4x8 and other construction stuff around, when I am doing a project. Overall, I'd say I am over $3K into HF stuff (mills, lathes, compressors, welders, on & on) and never had an issue.
The repacking of bearings upon assy is not an option, but a must, so it states in the manual. You'd also pump the rear of the wheel hub full o grease with a grease gun.
Anyway, I can not imagine a better trailer even for 7x in price. I tow it with my diesel VW Passat, getting around 50MPG hwy (!) - _with_ trailer/boat in tow.
Here's another pic showing the trailer with the rail extension out and used as a prop-up to have trailer on it's butt, for constrained spaces - the trailer footprint in this position is 4x3 feet (!)
