It was not effective as could see cockroaches around the electronic repellent and its of no use.

From the first date, I noticed the bed bugs are leaving their places and nests, it was not comfortable but I knew this device is working. In two weeks, all bed bugs have disappeared and it worked effectively. Since I have doubts that this device is safe for humans and pets, I decided to turn it off after 1 month I thought the bed bugs have left the room, but in less than 12 hours, bed bugs are seen and on the bed again. You have to keep it on all the time, you need to trust it is safe, and this device does not kill the bed bugs, it will direct them to run away, but where to? In my case, they were hiding in a deeper place away from the ultrasonic waves. However, thanks to this product, it gives us peace temporarily - until we solve the problem from roots (get rid of the infected furniture).

The material is good and it easy to use but unfortunately not effective in keeping pests away.

reduced the mosquitoes significantly indoors

Since using these twe haven't seen any cockroaches. Pleasantly surprised

Plugged one of these in and so far the rats got very noisy, but definitely starting to get them out of the room. Given it's ultrasonic, I unplug every day at night and reconnect it in the mornings, to prevent any side effects.
