Ogrow Aluminium Lean-To Greenhouse

Hi, I am a mechanical engineer who saw all the 1-star reviews bemoaning the assembly process - and I bought it anyway. For the first 30 minutes, I was amused at the cut corners - some of them, like the strut channel, actually can streamline assembly vs through holes (and it's cheaper to produce)! However, as time wore on and the metal-bending issues became worse and worse, I eventually found my frame on the verge of collapse so I'll have to grab some L-brackets and resume assembly sometime this weekend. That is, if the bending did not permanently damage the strut - which is paper-thin by the way. Assembly is a nightmare, there is no design consideration for leveling or weight distribution. No sub-assembly, no (or too few) brackets to provide structure. Maybe the thing is solid when constructed (doubtful), but assembly is literally not possible without a wealth of outside tools to prevent catastrophic failure. The "bolt-in-channel" design quirk is cute, but extremely inefficient to supply sufficient torque without stripping -- ESPECIALLY when the next step has a floating 6 foot pole attached on ONE end by ONE bolt. I chuckled that the majority of, if not all, bolts are designed to only slide in at an angle (because the designer hates the customer) AND the majority of bolts are not accessible for tightening up (because the designer hates the customer). I will give this another shot this weekend. Maybe, if everything goes perfectly, I can increase this review to 2 stars.
