Good Knight is a very well known brand. That is why I bought this particular brand. But, the performance of this cards are not up to the mark.
This card use to protect us from the mosquitoes but at the time of burning this card the smell of this card is very bad and dangerous for health. The product packing is very well and papers smells good at normal time.
But, after burning a bad smell comes from those papers. And It’s not work very long time.After few minutes they are all back.The cards are not effective on mosquitoes.It’s price very low and every stationary shops are sell this product but honestly speaking It’s just waste of money.So, I’m never recommended Good Knight Advanced Fast Card.
