Ultrasonic Pest Repeller, SENQIAO Electronic Plug-in Insect Pest Repellent Indoor Pest Control for Spiders, Mouse, Insects, Cockroach, Mosquitoes, Mice, Fleas, Flies, Ants, Rodents

I purchsed these based upon the reasonably high scoring reviews; however I need to let people know that I have absolutely no evidence that they work; but equally no evidence that they do not. They are chinese made and as such they do not understand that the earth pin on the device needs to be longer than the other pins; we found it very difficult to actually plug them in. We had a mice infestation and using the devices in our loft; plugged in an extension lead; the infestation did not get worse and they remained in an area away from the devices but they did make the mice go away; hence my comment that i do not know whether they work or not. After a period of two weeks we eventually resorted to poison and that was very succesful and quick acting. My advice; if you truly wish to get rid of the mice; is poison.

Me being ultra sceptical about these kind of devices I thought oh no another waste of money but O.M.G this thing actually worked. I have 8x10 yardmaster steel shed that I had a regular visitor ( a mouse) during the summer months which I thought was ok as he only stole bird feed and went back to the fields at the back of my house but little did I think he would turn my shed into a HMO. I ended up with loads of them living in anything they could find. I asked pest control who said to put poison down to get rid of them but feeling guilty that I probably encouraged them in the first place I looked for a more humane way to remove them so opted for one of these devices which was placed in the power socket. I left this for 5 days and then gingerly entered the shed expecting mice still there BUT to my amazement they had all left not a single mouse to be seen even pulled out the stuff they were living in still nothing. If you have a mickey mouse HMO then this thing WORKS !!!!!!

I bought 2 pcs and both did not last 1 year. One lasted 8 months, the other lasted 10 months.They are both dead now and Amazon does not offer replacement or repair.The return was only available for 2 months.I understand the manufacture has an obligation of manufacturing warranty for 1 year but Amazon or this manufacture do not offer any.I cannot tell if the device was effective for the purpose but it is obvious that they are both dead(no grow led light).Stay away from products such as this for not wasting your money.

So far so good. I have a lot of different types of the same thing. Overkill I suppose. The writing on the box is not very good English, grammatically incorrect and spelling also.

It does NOT work on Fleas. One week later, my cat still has Fleas crawling on her. Disappointed.

Bought this few months ago.it seems tp work.have not heard mice for a while.i would recommend it.i read the rewiews & bought it.easy just plug in.

I have had this plugged in the kitchen for about three weeks and thought I had got rid of my problem mouse, but to my horror to-day i watched as one tiny mouse sauntered all around the kitchen looking for food (of which there was none) this product was a waste of Money !!!!

Used as directed, but completely useless. Three months in and the mice go past it without a care. A waste of money and I was a sucker to believe any of the reviews. It can’t be that something like this works for some and not others. Either it works or it doesn’t. This doesn’t.
