Review on Ultrasonic Repeller Repellent Electronic Mosquitoes by Robert Johnson

I didn't think ultrasonic bug/bug repellent was effective until I tried it. I used to only use insect repellent. But it turns out there are dead bodies in the house, but the bugs are still there. It was very inconvenient to clean up the dead insect bodies, especially in the summer when they all crawl out. Compared to other ultrasonic repellents on the web I found this one to be cheaper than others and it is of good quality as I have been using it for over two weeks. No more dead insects and no more flies in the house, definitely recommend to friends
