It looks and feels very sturdy. It has been in use for three days and I have not seen any issues with diminished draft. I appreciated being able to use the offset to complete the installation without altering the existing hearth.

Solid piece, has more adjustability than other offsets. Also has trap door for clean out. Very happy with it

It appears to accomplish my offset issue with chimney and my insert very well. The quality seems very good. Hopefully it woks well over time. My only suggestion would be to allow the two collar centers to be closer then 6".

Solid box, liked clean out door . Bought because inner volume is somewhat bigger than competitors .

Worked fine
