Mosquito Repellent, Plug in Ultrasonic Pest Repeller, Electronic Pest Control 2 Pieces for Mice, Flies, Roaches, Bed Bugs and More by Ansbro

I originally purchased this plug-in outside for when we are sitting out on our back deck so we don't get attacked granny B's or mosquitoes and I didn't realize it came in a pack of two which is great so I actually plug one inside and one outside so that we don't get any little critters inside either. So far so good hoping this really works this summer has I don't like have a little critters come inside at all.

I purchased this with the hope that it would cut down on the amount of Roaches that come into my house but it has not done that in any way. I truly wished it had, for me it was a waste of money and a big disappointment.

No way to know if this thing works. I used for bed bugs, and these certainly didn't get rid of them. Did they slow them down? Maybe? Where would they go anyway? Another room? If you want more questions than answers, buy this product.

I really have no idea if this device is just a placebo or not. I've had them plugged in for three weeks, and I still get the odd mosquito, so it's definitely not 100% effective. Still, can't hurt to have them plugged in, and they're cheap enough to buy and run.

I have roach in my kitchen .It almost summer now.So this is really work for me.And I put one in kitchen and one in living room.It is safe and healthy.Recoomend for other customers.

Have had fewer bugs since I got these. Works as promised.

Great repellent for those who live in a wooded area. I'd buy these again and would recommend them to all.

These didn't work. I actually got bed bugs about a month after using these.
