These guys are very knowlegible, professional and honest.
They seem a bit pricey, but offer full uncondtional warranties, which makes it a fair value.
My only comment is they could use more people. My installation got stretched out, because the technicians had to take care of incoming sales prospects, and it took an extra hour and one half to do the job.
Overall, I would endorce them, as I have full confidence in their products and workmanship, and I do believe them to very honest.
