Are these units supposed to flash? No one has mentioned it in the reviews so l thought the lights on them would be static like the one l had previously. Be careful when removing these units from your sockets, the reason I'm replacing mine is that one of the steel tips has come off and got stuck in the Socket!

I bought this to "eliminate" rats in the office. But, Rats party never stopped. They even run over this device, probably enjoying the Ultrasonic music!!

Crap don't buy doesn't do anything.

So badly made it won’t plug into most of my sockets. Poor English translation of ‘instructions’‘May single click the pressed key closure health breath lamp’ for example. Shoddy plastic body; is it safe to leave plugged in? Which makes you wonder if it works at all! The ultrasonic nature of the device of course means you just don’t know.

After buying multiple traps, bruised fingers setting them, missing traps presumably dragged away attached to tails and 32 mice caught, poison bait bags that supposedly are sufficient to kill 40 mice, these were a last ditch effort. To say im sceptical about something you can't hear and have to believe a blue light means they are working I have to say I've not heard any further scratching or movement for the past month. Wether it's too early to have 100% confidence only time will tell however what is apparent is the noticeable absence of spiders and flies even with open windows

When the weather started cooling the bugs started creeping…inside…my home. I researched nontoxic ways to mitigate bugs and these pest repellers were answered prayers. They cover a great deal of square feet and I don’t have to deal with spiders, crickets, and the occasional roach that wants to try and creep in from the neighbors house. I loved this product so much that I bought some for my family (fleas trying to ride in on their dog) and they haven’t had an issue since. If you’re looking for a nontoxic bug repelling solution - THIS is product. Very satisfied overall.

At first I was waiting for a quick result that the mouse would leave the house quickly, but it didn't happen. The mouse continued to walk around the kitchen and teased with her presence in the evenings. But after a few weeks, the appliances connected to the sockets really showed effectiveness as a result the mouse left the apartment

Initially, my fiancé and I were skeptical. We really didn’t think a little plug in with a blue light was gonna save us from annihilation at the hands (or should I say legs?) of these pesky buggers. We tried EVERYTHING! Bug zappers, glue traps, apple cider vinegar traps, etc etc. Why not give this a try??So we waited the first week.. then the second week.. and then we just forgot about it. About a month or so after, my fiancé asked me “hey babe, I haven’t really seen any critters lately.. have you?” I hadn’t seen any in over a week!! It’s been a few months already and they still work great. The fruit flies/gnats are gone. The ants haven’t been strolling in from the cracks. And the creepy centipedes or fuzzies as we named them are nowhere to be found.I’m not gonna focus on the technical stuff. I’m not gonna sell you on the fancy blue light. It’s got a small footprint and it works! Just be patient and see for yourself.
