Recently purchased a Walmart Surya 4 burner gas stove. The product was supposed to have high efficient brass burners but came with very light alloy metal burners. disgusted went for return as it was supposed to be easy. but surprisingly the courier people wont even certify whether the packaged item was in good condition etc. once bitten I was really scared losing my money altogether. thats amazing amazon. ek bar try karke dekh liya, dobara zindagi mein kabhi nahi. buyers beware.
