Power sells mediocre doors and windows at exorbita...

Power sells mediocre doors and windows at exorbitant prices. They will waste 3-4 hours hard-selling you on the merits of their customer service. They think if their service is above-average, they can overcharge for a product. Their service is average at best, pre-install, and horrendous post-install. Here's my experience:

$3000 for a back door (Equivalent to $1000 from anyone else)
Wrong door was installed.
They sold me on their fancy window technology, which my door is missing, which is a bait-and-switch.
The wrong hardware was installed on my door, twice (fix was wrong too).

I think they're a multilevel marketing firm that happens to sell windows and doors. Quality products don't require so much effort to sell.

EDIT: After 18 months, the trim around the base of the door is swollen and mildewed because of inadequate sealing during install. These guys are the worst.
