I bought this coop in January 2018, so it has just turned four years old. The run is 5 stars! The design of the coop is 3 stars, the wood quality is 2 stars. I put the coop itself on the ground on a rubber stall mat that I purchased at the same time. In the four years I've had it, I rebuilt the four lower doors last fall as well as stained the entire coop. If you purchase this, stain it immediately. As said by others, a few small forward-thinking improvements will make this last a lot longer. First, buy a rubber stall mat for the coop to sit on. . Saves the entire bottom structure. Second, stain and seal it immediately. Third, use butyl tape or weather stripping to plug up the gaps. Fourth, reinforce the interior with a board between the two trays. This keeps the poop from getting built up and under the two trays. Finally, reinforce the roost bars by nailing flat boards across the top. They are not wide enough.

I came out yesterday morning to find that something (raccoon maybe?) had pried off the vent on the back and killed all my chickens. This product utterly failed at it's one job.
