I talked to someone from customer service before my purchase, then a person from technical support after my purchase. I cannot tell you how refreshing it is to talk to people who know their job & care about customer service. You have, by far, the best prices I found on the internet for the American fireglass products. Thanks for the great shopping experience.
By Sallie
Great product. Went together super easy (a screwdriver and my 50+ year old lady hands and decent directions.) Absolutely beautiful product -- helps prevent the wind blowing the flames flat. ALSO -- I was very impressed with the packaging. Minimal and secure. Everything arrived in one piece. A+ all the way.

We received our gas firepit glass guard 5 days after ordering. We love it and glad we purchased it. Was a little skeptical when I did not receive a shipping notice and could not talk to customer service but they answered my email promptly. Very pleased with our purchase.

I'm in the process of building a linear fire pit and need some advice on the different types of burners and their connections. The service person I talked to was very helpful, he gave me all kinds of do's and don'ts on installing my burner. His help and advice was very much appreciated!

Easy ordering, quick and friendly delivery, product was just what we ordered and price was very comparable if not cheaper than others we searched. Would highly recommend and use again if needed. Thanks
