A friend that was having a major pest problem. (You know it is true love when you go shopping together for roach motels, yes?) We'd had good luck with the smaller model Weitech 0520 -- but needed more coverage. The critters had moved from the kitchen down a long hall to the bathroom. (brrr!) So I went back and got this model too -- thinking bigger was better! However, where the smaller model constantly cycles between high and low frequencies, this model has a switch. It is set at high or it is set to low. Low gets rid of mice and rats -- high gets rid of insects and spiders. So! If you have 4, 6 AND 8 legged critter problems, then this is probably not the right device for you -- or maybe you want to buy one and set it to high and buy another and set it to low. It does have the advantage of operating on battery or AC power... so if you have a crawl space or attic without an electrical outlet, then this would be the device to buy. But get one if you have a rodent problem -- plus another if you have a bug problem. They really do work. Amazingly well. My friend moved this one out to the garage where the four footed creatures were getting in the dog food. He then bought two more of the smaller models (Weitech 0520) and moves them around the house. Hadn't seen hide nor hair of the critters since.
