Was told product was a US made product. Box says "Made in China." Was told that the product was limited to stock on hand (40 boxes) and no more was available - our project would require all of it. Installers carried away multiple unused boxes and left a full one for future use, if needed. Installers said stock was NOT limited. Must've been a sales tactic. They won't lie, would they? Still waiting for office staff to send a copy of the invoice. Installation was completed a week ago. Called and was told I needed to talk to the bookkeeper. Guess what? She's not in and they can't (or is it won't?) take a message.
