Bought 2 of these cans within two years. Size is perfect for most single-family homes - two of these will hold an enormous amount of trash.
Tough plastic body withstands the abuse of automated trash trucks. Lid is pretty lighweight, but secured with a very hefty hinge. Stays flexible in sub-zero temps, so it shouldn't crack like cheapie lids. Convenience of an attached lid is awesome.
Wheels are larger than most consumer models - less pushing effort and it's easier to roll down steps. I could use even larger wheels, since I push these through heavy snow down a 200' driveway. Still easier to move than most wheeled cans.
I had a problem with one of the cans after about 1 1/2 years of steady use. One of the end caps that secures the wheel to the axle worked it's way off and disappeared, causing the wheel to fall off. It was repaired easily by installing a washer on the axle and securing the wheel with a small hose clamp. Doesn't look pretty, but it holds better than the original cap - which was just press-fit onto the axle.
A minor annoyance: the wheel wells intrude on the interior of the can. It doesn't lower capacity that much, but can sometimes make it harder to stuff that last bag in and close the lid.
UPDATE: 12/2013 Wow, Amazon's current price on these cans is less than half of what I paid for mine several years back. I'm bumping this up to 5 stars, based on value alone.
