One of them went out and stopped working within a couple weeks and came apart in another instance. I've used products like these before and they do seem to work pretty well, however it really depends on which brand you go with. A lot of the brands can be cheap and affordable, however sacrifice quality as well. I wish I could order the same brand I originally had since they're going on strong, but unfortunately they're just not available anymore or are crazy overpriced now due to their rarity. Coniso's quality just isn't there. Hope this helps.

I am very impressed with this product. Since installing these, my mother in law hasn't dropped by yet. Actually, she's a sweetheart and I love her.It IS rare that I do see a pest in our house now. When we do, it's dead. I've bought additional pieces to have in each room as well as a set for the mother in law. Hers doesn't work as well as I still tend to drop by and visit her. However, her creepy crawlers have virtually been eliminated.

The mouse in my kitchen walked by and laughed at it. BUT, he wasn't laughing when the D-CON trap got him!

I have had mice infestations off and on for a long time. I put 1 in the kitchen, 1 in the living room, 1 in the family room, and 1 in each bedroom. These actually do work. No more mice.

I wish I'd been able to video the mouse walking back and forth in front of this device plugged into the wall. Wanted this to work. Does nothing.

I used it for a couple of months and I didn't notice a difference. In fact, I felt like I had more bugs in my house.

Very happy. These work.

I have seen no difference.
