55 inch tv in rs 40000 is not a bad deal .I had just bought it some day before after a long try in a sale.
It has 2 usb ports and bluetooth connection and wireless connection is also available.
Sound quality is not so good as you expect from this tv may be you feel bad for this.
It has also 2 gb ram and 8 gb internal storage and 64 bit quad processor.
Its attractive look and view make fall you and you will feel love after watching and viewing tv .
So if you want to buy a tv then mi led tv 4 is very good deal for you.
