Discreet Ceiling Mountable Battery Operated Ultrasonic Rat and Mouse Repeller

Believe it or not the "gadget" works.

I'm not really sure about this product, my mouse problem is still not resolved but not as bad as before so maybe, I hope just needs more time. Easy to use and install in my loft.

Bought 2 of these to put in my loft after rats nesting. These were in for 2 days and we didn't hear a thing. I set up a blink camera, its been 3 weeks now and nothing has set it off. Great product!!

I put this in potting shed where it sits on a cross piece of the back wall, facing into the shed and about 3 inches from the floor, unobstructed. It sits there flashing nicely. I also have two humane traps for the shed, which I bait with a bit of cheese or a peanut most days. The trap that sits about 2 foot from the mouse repeller has, I admit, never had a mouse in it. The one half way down the shed, i.e. 5 foot away, has a mouse to be let go every day. I'm thinking of giving each mouse a squirt of dye as it leaves to see if they are the same ones coming back! I am taking them 100yds or so up the road to let go in a field.

Placed in my bedroom as the pesky mice have been travelling through my home.Hoping they keep away from my room.

Can’t tell the overall effect because I’ve not had it long enough. Works as it should though.

While easy to set up and install, this made absolutely no difference despite being deployed in the downstairs bathroom which was point of entry of rats into house- might as well have played them Radio 4 for all the good it did!

Devices which use very high pitched noises to repel pests seem to be controversial, and some may be unreliable. However, this one worked perfectly for me. Within a couple of days the mice I had heared in my loft had gone, and after two weeks have not returned,
