Works at first... not built to last.

I bought mine in 2004, and it does suck in the mosquitos- but this summer (the beginning of my 3rd summer with it), it wouldn't start. Sent an email to tech support after I have done everything suggested on their website- they have no useful information, and tell me that they can do a 'tune up' for $130, and it comes with a 1 year warantee. I figure that was way too much, so I decided to open it up and look around the inside.^M

Overall, I'm not impressed with the build quality- the electronics inside are not protected, and many of the traces were oxidized and/or delaminated from the PC board. Considering this is something that is to be used continuously outdoors (and only outdoors), at the very least I would have expected it to be conformally coated. It isn't. The electronics are only protected in the most basic sense- from rain directly on the PCB. Otherwise, it is open to the environment. The sensor that serves as the heat detector (which tells the device that the CO2 is being generated) is held on with a plastic screw- and it is quite obvious that the screw failed due to heat- I found the head in the base of the unit, discolored brown from the heat. What's left of the screw is brittle plastic, and stuck in the manifold.^M

For the price of the unit, I am definitely not impressed. While it does catch mosquitos, the unit is not built to last much beyond the warantee period. If their tune-up was a bit more reasonably priced, I'd consider it. Considering the price of the unit, it is probably better to think of the whole thing as a disposable item, and replace it with a newer model (or try out a competitor's product).

The others are right

It worked great for one season but when I went to start it up for this season it wouldn't start. I did everything the manual and website said to do when I put it away last fall and did everything the manual and website said to start it up this spring, including wasting three of the "clean out" cartridges and it still doesn't work. Plan on buying a new one every year if this is the one you choose. Their tech support does not answer emails and the wait for them to answer the phone is nearly endless.^M
Bottom line: avoid this product.

The 18 month wonder

The first time I tried to clear the unit I had a l-shaped adapter. Damn thing blew apart. Low and behold, they had a different design, now. The unit worked ok for abot a year and one-half, then I started getting the famous error light flashing. I cleared it four times w/co2, got a new tank of popane, reset the regulator. The whole nine yards, but nothing worked. When I called tech support, all they could say was that it was an internal problem and to send it back at my cost and they would send me another at $130 = 19.95 shipping again. Then I said that's not bad for a new unit, to which she replied that it was refurbished. I asked why the could not send me the internal parts. Can't do it. Hey, what a deal. I passed on this golden opportunity. Maybe someone else makes amore reliable unit that does the same function.
