OZRY Ultrasonic Vermin Repeller - Newest Home Control Professional Plug and Play Electronic Vermin Control Ultrasonic Repellent Indoor usage for Bedroom, Kitchen, Living Room (6 PCS) (White-01)

It seems to work quite well. It does not work against the flies. But quite good against other insects. It is small, quiet. We use it in the whole house (kitchen, rooms, corridor).

Got rid of mice, and bugs even when doors open. Got rid of all the ants in my air b and b no matter what is left out from guests!

I can’t hear anything when I plugged these in. I thought I would hear a low noise but nothing. And so far I haven’t seen anything. I even plug one at our cabin and so far so good

There are six in one box. I use this to control roach in my apartment. It does work for several days. I see less roach in the kitchen. But it need electric, which might restrict its use in some area with no plug ins, like bathroom.

Out of 6 units one stopped working very next day and one more stopped working today.Can not see any improvement in the house.

This Ultrasonic Pest Repeller is very useful. It's killed many bugs and spiders. The light on it is really bright. So far so good, no issue. Very good quality.

Great value. I got them because I saw a rat in the garage. So I out two in the garage and I haven't seen any yet. I'm hoping they're working.

We placed these in our kitchen where we often have fruit flies. Since placing them, I haven’t seen a single fly ! They’re silent also, you can’t hear a thing when they’re plugged in- unlike other pest repellants I’ve used in the past.
