Bought this burner around 4 years back and since then every month some problem or the other arises in it. The after sales service is pathetic. My automatic gas knobs stopped working within a year itself and have to use the lighter to ignite the flame. Keep requesting rhe service people to change it but they I feel have no knowledge about it. I am literally regretting my decision of buying this burner. Thought sunflame to be a trustworthy brand but I am highly disappointed.
