The normal mode is not so effective to kill the mosquito’s. But the active mode performs better relief from mosquito’s.I use it way back in 2015 but now-a-days, I feel it does not works very well.it is not at all effective and frankly saying the smell or the fragrance of this product is also very bad.it is easy to use you just need to plug the device In and you are on the go.the price is also high like you can get 100’s of other option with in this price-point.so I personelly think it as waste of money.I’ve been using the Good night products the product quality slowly started & very dangerous for all childs.
