I have bought this product before 2 months. I am surprise with the microwave that is concentrate in the centre!!
If you want to roast papad and you place it in the centre of the tray it will burnt in the centre and outside range will not roast (Kachcha rah jayega).
I complaint to the cust. care and the engineers says it will do. you have to put microwave stage proper first but no one visits at my place. So I can say that the after sales service is very very poor.
As per my knowledge microwave heats each and every corner of the particular food not only in the centre.
So my recommendation is please don’t buy this product.
