A few things changed during assembly

For the price OK, really I have to say that I have not purchased the greenhouse here on Amazon but on another platform, but with the same provider. A portion of the door was missing, but was replenished quickly and easily. Without much to discuss or bla bla. The staff are very friendly, as there is nothing complain about.

Equal first, the instruction is actually almost for a ton. I personally consider myself a very good DIY and professional, but the manual Read me first gray hairs. However, if a start is made, then that's still relatively quickly.
I have also previously bricked a foundation and then the steel frame pegged it firmly. The lower aluminum frame I have something else attached as described and then screwed directly onto the steel frame. After that the building was a breeze. And alone. Not as described with 4 man and without both gables and side panels on the ground pre-assemble. And in 6 hours.
The greenhouse is super stable since wobbles nothing more.

What I absolutely do not like having the nuts and bolts were partly moldy and the attachment of cellular sheets by clamps. The nuts and bolts I have subsequently again painted with zinc spray, and the steel frame for safety's sake, the way concrete foundation, with a sausage bitumen (so to speak as a silicone joint) sealed from the cartridge. After interior and exterior painted over with String bitumen. I think that is so well protected against corrosion. Since I had some doubts that is the galvanizing sufficient.

The cellular sheets I still additionally screwed with stainless steel screws. The holding now and rattles also nothing more.

As the plates will behave in the coming months / years show. I hope that will last a few years and are also UV-resistant
as advertised.

As written, do the same build some thought, then the thing is stable and it clatters nix more.
Then it's perfectly okay for the price. For people who are technically he does not, or poorly endowed, this is more of nothing ....
Yet little tip: just create all bolted, only put everything in the end. Cordless Screwdriver with 10 nut and a clever 10 open-end wrench for ease your work enormously ;-)
