I bought this model in 2004 for my New England home. It is very effective in catching 10 to 20 mosquitoes per night. After a month the numbers dwindled to about 5 to 10 per night. Possibly, because the mosquito population was collapsing. I apply the CO2 cartridge and change the Octenol lure only once at the beginning of each summer. I also turn it off every morning and turn it back on during the evening because it doesn't catch any mosquitoes when the sun is shining hot. I haven't had any problems with it breaking down for over 5 years. Perhaps, I got lucky with a good unit. Or possibly, it is because I turn it off every morning and this keeps it from wearing down.

Pros: Effective in catching mosquitoes consistently. Lasted over 5 years and still working.

Cons: The power line is starting to fray at the connector.

Overall, a good product. Would recommend.
