I bought a "pest free" plug in unit (the old rectangular shape) in September 2000 as, at the time, we had rats in the attic, small field mice around the house, cockroaches and spiders. The pest free has now been happily blinking for ten years and, we have no rats, mice, cockroaches and, only the occasional spider. For us it has done all it was claimed it would do; we've been very happy with its performance and will certainly replace this unit if and when it finally gives up the ghost. Should you be interested I've attached a copy of the invoice covering the purchase on 4th. Sept. 2000. which we bought on the recommendation of a friend who had also been extremely happy with the unit.
