Hello Friends, Today I am going to share my opinion and experience about Good Knighy Advance Action, Which comes at the price of rupees 110( approx) .which works as a mosquito-repellent.it was working fine when 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.
