I've had this for a few years now, and have happily stored my 30" snowblower, gas lawnmower, 2 large trash cans, a recycle bin, and a yard waste bag. Lots of room, and the slide roof makes things easily accessible.

Biggest complaint is over the lack of rigidity. If you don't properly flatten and compact the base it's sitting on, the walls will easily twist and misalign. The roof slides on rather precise rails, and only a small amount of deflection will keep it from moving freely. Also, the hinge point integrated into the doors is a weak point, so if the door doesn't have ground clearance to swing easily (like if you don't shovel snow away from the doors, and just try pushing the snow as you open; or if the ground rises in front of the shed and the bottom of the door scrapes constantly), you will most likely pop the seam in the door at the hinge point.

But, like I said, if you prepare the area well beforehand, you'll have a roomy and convenient product for a long time!
