Ultrasonic Pest Repeller 2 Pack, Insect Control, Spider Repellent, Plug in Indoor Mouse Deterrent, Anti Moths, Ants, Bed Bugs, Fleas, Cockroaches, Flies, Spider, Wasp (Classic 2 Pack)

I brought these couple days dgo, and it really works straight away, easy to use u just plug it in. Worth the money. Good quality

Seems as though they actually work , kills flying bugs , easy to use and non intrusive

Arrived very quickly , small and compact . Put it use straight away . Will have to see if it works as had 6 wasps in livingroom in past 5 wks

Not clearing dog fleas had 3 weeks and still finding fleas

Not very loud (68dB vs 110dB uncalibrated for Queath-branded triangular pyramid with strobe lights), and the signal is a pure-tone that ascends in frequency by about 2Hz every 3-5 seconds (unvarying, I just didn't time it accurately). At the frequencies shown in my picture (red are the peak levels after I waited for it to complete a sweep and start at the beginning again, white is the level when the image was taken, showing a 2nd harmonic at about twice the fundamental) this unit will be quite directional, so has to be placed at the right height and facing offending critters. On the plus side it should be totally inaudible (I can't hear this, but the Queath unit is LOUD - but I wear hearing aids).

I am very pleased with this item. The quality is excellent and it was exactly as described. It feels durable, well-made, and has met all my expectations. Considering the price, I believe it is definitely worth the money. Overall, I am very satisfied with this purchase and would recommend it to others looking for good value and reliability.

Yes these seemed okey.

We bought them more than a month ago and we are very happy with them. We put one in our kitchen and one in our bedroom and up to now we saw nothing coming into our house. It’s winter and can’t say what will happen in the summer but even so, up to now many insects came inside our house. Spiders, small insects even snails. Now nothing and we are very happy indeed!
