I bought a greenhouse. Be careful with the wind.
I installed it as instructed and the plastic tore from strong wind.
There is no warranty for storm damage.
The greenhouse needs to be additionally secured with reinforcement hooks and zig-zag wind cord around the roof. That way, it's fine.

The assembly was relatively easy.
There is an instruction manual in the package.
Its construction is not sturdy.
Personally, I reinforced it along its length with wire at four points in order to tie it better as a structure, and additionally, a plastic mesh will be needed on top before the hood is placed to prevent it from holding rainwater.
The hood cover is quite good as it seems. Its durability will show.
