I am hoping it last 2 to 3 years.  There's some bubbling on the roof shingles. I didn't realize it had no inside.door to close the coop off. We went and cut wood to fit over the opening,  grabbed higdes and locks. 
The hidges to the ramp were plastic a broken. I had to go to Ace and buy some. We had to use better screws. Put a better lock on the run gate. 
I knew these were cheaply made. But this topped the cake in cheaply made. 

I'm glad I only paid $350. No way is it worth $500. 

I keep 4 bantams hens and a bantam rooster in it. Luckily my full size girls have a coop I bought at a local shed shop.
