Despite the pandemic and closure of their sales office, relying on phone and customer pickkup, our experience was far better than the average and, strangely, very different from other reviewers' experiences.
After describing our needs, the salesman gave us options on materials and the technical information we needed to make a good decision. Our material was cut and ready the next business day, and fit perfectly despite odd sizing.
Finally, the price was significantly lower than the next lowest quote. I didn't ask how they can do that, but that certainly was appreciated.
Our experience was "excellent".
