I am very happy with your product. The attraction for for me was the fact that it was adjustable as I had constraints about where I wanted it to fit. The adjustment of the posts both sideways and depth wise were enough that I thought I could fit it in my available space (I've worked as an Aeronautical Engineer all my life so I figured I could "make it fit" given the dimensions available). I had no problems erecting the structure. The hardest job was drilling the holes through the brick pavers into the concrete slab beneath, but that is not related to to the product.
The quality is excellent, and the value is good. Bunnings stock this item for ~$1500 but only in white (sigh ;) ), and I wanted grey. I found 4 websites selling this, but for three of them it was either out of stock or discontinued. Such is the limited choice in Australia due to the small market. Your website advised to call first to check stock, which I did, and you had two left, one of which I bought.
The only problem I had was with the roof panels. I followed the diagrams in the installation instructions initially and had problems with the end panels which kept "popping up" at the outer corners. I then reread the installation instructions (as an engineer does), which said to start installing the roof panels from the middle (different to the diagrams). I then took off all the roof panels and installed them again from the middle outwards. I still ended up with a problem of a panel "popping up" at one front corner. I manufactured a packer and played with the fastening of the beam that the roof panel connected to, and it has been OK for a few weeks now. The problem (the engineer in me is speaking here) is that as more roof panels are added, they are 'tensioned' and apply greater tension to adjacent panels. This induces the roof beams that they connect to to twist, which results in the formed edges of the roof panels being unable to clip into the top of the beams properly.
I am fortunate in having an engineering background which enables me to solve problems I come across, but I suspect the average handyman would struggle a bit with this product.
All that said, I'm very happy with the product. It's just what I wanted.
