Rated 1 out of 5 by from Poor quality product There is a reason for this being half the price of the Honeywell one. It is nasty, and worst of all it sticks open as the plunger attempts to return to its seat. Took it back for a refund. Of course I may have just got a did, but I would check yours thoroughly before fitting.
