Good Knight is one of the popular brand for mosquito.Good Knight liquid does not help in repelling the mosquito's.The mosquito's will be present in the room even if we keep the machine on the whole night.This product is useless now, but before it was effective and now their quality has degraded and do not give the quality we want.Now adays our first choice for mosquito's is only one brand Good Knight.This brand product is no more powerfull now.I do not recommend Good Knight Mosquito Repellent, as it is bad for health and even it does not give the quality.
