Was easy to assemble and the quality was as expected.I am 6'6, 350lbs and needed something that I can rely on to not be more of a hinderance than benefit when rolling around under equipment in my shop. I was skeptical when I purchased but now, after several months use, I am pleasantly impressed.The Creeper is as comfortable as you would expect it to be. Much more comfortable than any other I have used, due to my large frame.I am used to the wheels of other creepers to stop rotating or get stuck on the smallest piece of debris on the floor, not so with this one. The wheel mounts are sturdy and have not broke down. I will probably upgrade the provided bolts and washers at some point as I believe they are under-sized.I am also used to other creepers bending in the middle and scrape along the floor after prolonged use. I've had zero fatigue or sag out of this creeper so far.This was a very good purchase and I will buy more.
