They work and they work really well. This is the second set we have purchased to add coverage to the first set. Unless you hit them with a baseball bat or something similar or have a lightening strike, they just keep on working, and our experience is they keep on working well.

We have big broblem this year with "Boxelder Beatles". I dont know where they are coming from, but they get in somehow. I purchased these "Bell & Howell" Pest Repellers and plugged them in all over the house. Even after several weeks, they haven't repelled anything. We're even having to deal with more than our share of spiders. It seems like these repellers are actually an open invitation for any and all pests. NOT HAPPY AT ALL WITH THEM!!!

I have had this item for about a week. When we opened the package the two small units make noise so we are unable to use them. We are still seeing bugs so we aren't sure at this time if they even work. I will know for sure in about 2 more weeks but seriously doubt they will work.
