I spent $5K on the i2700. It is beautiful, well built and super difficult to get any draw. This unit is for someone who is heating their house using wood NOT someone who wants a cozy quick fire in the evening. More than 50% of the time my house is filled with smoke. The unit doesn’t completely seal, so instead of smoldering smoke going up the chimney it comes into my house. It is not just me being inept, the techs at my Dealer couldn’t get it lit, nor could other friends with inserts. Only the owner who has one was able to get it lit. And because its not “defective” there is no recourse although I’ve complained since day 1. Total waste of my money. Tried talking to Regency Customer Service and they “don’t deal with the public.”
