Could'nt believe how fast it was shipped to my home! High quality liner. For a woodstove application, we wrapped it in the insulating blanket and dropped it down the chimney. The only thing I would say is measure exactly how long you need and (make sure before cutting...no "measure once cut twice!") make your cut STRAIGHT, I used a sawsall, worked great. Overall great product, fast shipping! Will be ordering another in the spring for the oil burner chimney!
