1st the picture looks like it has plastic wheels, the wheels on the trailer I received are steel which automatically gave it one more star. The ease of assembly is worth two stars for sure, 9/16 wrench and a Phillips head screwdriver is all you need... and 20 minutes. The tires are basic but I am betting I get a few years out of them. Very sturdy build, with the tilt and swivel feature for dumping all at an affordable price.
I have not put the trailer through its paces yet, no heavy loads of dirt, but I am betting the weak link will be the guy shoveling the dirt to fill it.
