Review on DiversiTech CVENT 2 Concentric Vent 2: Efficient Airflow for Optimal Performance by Doug Hook

This review was written on 15 March 2014. I was told that this manufacturer uses OEM. Part of an OEM kit only. The size tolerance of the pieces was good - easy to dry and glue together. The instructions are printed on the box, which seems a little crazy, but I still mostly relied on the device manufacturer's instructions, as it can be used in many configurations. I am not affiliated with the seller or manufacturer and do not receive any benefit from anyone in connection with this review.
