The device is a bit cheaply made (plastic) and not durable at all. However, it seems to be working fine. It has a sufficient length of power cable and a sufficient length of plastic exhaust pipe. Until the plastic tube melts. The CO readings appeared to agree with those from the New Jersey State Inspection Station for CO. I've only used it twice and will come back at some point in the future to adjust my rating.
