We bought this sled last fall. Has to be one of the fastest plastic sleds we've owned. Has lasted us about 20 sledding trips--we're pretty rough on it. Nice long, flat, low friction bottom. We consistently slide much farther than any other folks at our local city park sled hill. I'm 6'4 and 250, my wife is 5'8 and...full figured. The 2 of us and our four year old son can ride it at the same time, with a bit of squeezing. Makes a decent toboggan for dragging the kid on short snowshoeing trips. And like the previous poster, the bottom is holding up to the occasionally skip across the shoveled/paved sections of the park or paved mountain roads.
But, we left it leaning up against the house--partially covered in the shade--over the summer-not very smart. This year, my son cracked a chunk out of the back stepping into it...still usable. May have been a result of the storage conditions, but I don't think it should have broken this easily. Otherwise, it's been a great sled.
Turns out it was junk. It literally broke on the first run down a hill. My 8yr old was in the front and I was behind her. We went over a small bump and the front curve shattered. I just don't understand, the weight was ok, we didn't hit anything, and the temperature wasn't even that cold.
