My trawler came with a non-working Bilge Buster BDC-400 installed. It was not high on my list so I ignored it as I finished other jobs on the boat. Today I finally removed it and called QuantumAir. My unit it turn out was purchased in 2002; I bought the boat in November of 2004 and it was not working at that time. It worked for maybe two years at best. In the last three years the company was sold to VR Industries They use the same name and telephone number, but will not support or repair any of the units older than about 2004. Their representative told me that they changed the board and design. I decided to open up the unit and was shocked to find a tiny circuit board, a couple of power transistors, a voltage regulator and transformer and a handful of resistors and caps. I have no idea how you get the units cost out of such a small number of parts. The board was not coated to protect it in a marine environment. They did offer 20% off a new unit as a "previous customer" discount. I may try to get it working by changing some parts, but I am not sure it is worth the effort, as I have a larger room size unit if I ever need it. Joe Urban Punches - Monk 36 Lancaster, VA

I returned it in August for a retrofit to a newer version emitter, it cost $99 plus $12 S&H. I returned it twice more, since then, and finally have it installed and working. Despite the problems I had getting it to function, it really does work as advertised. No odors. It really keeps the bilges fresh. I did have the cost of shipping for 3 trips, but no additional charges for the service. I'm happy with it, but I can't honestly say it would be high on my list of things I'd have do have if it hadn't been on the boat when I bought it. Steve Sipe Solo 4303 "Maerin" Upper Chesapeake
