I bought this after recently buying and assembling a "glory" greenhouse by the same company;
While the greenhouse is sturdy and well made this isn't so. The instructions are a challenge as you must figure out the pictures since there is little written information.
Make no mistake, the construction is flimsy even after securing the assembled shed to a sturdy base. Pushing lightly on any corner , even after re-tightening all screws and bolts will cause the door opening to assume a a trapezoidal shape. The material is very thin as is the aluminum frame. Once assembled it does have a nice appearance but don't expect it to keep much of anything secure.
