Good Knight is a bad mosquito repellent. It has no effect on mosquitoes. Mosquitoes keep flying around the room when the mosquito repellent device is ON. The worst thing about’Good Knight Mosquito Repellent’ is its effect on mosquito is less and its effect on human is more.
When ever I put this device ON and sleep, I start coughing not only me most of family members feel allergic to this. The results are poor
Though its user friendly and easy to use but no effect on mosquitoes. And top of it its expensive.
