This is an cost efficient AC(Checked all the online and retail stores) one of the cart offer was good. However the guy from LG customer care suggested to buy from the retail store or showroom.
Thanks to cart customer care for excellent support - Delivery in two days and Installation in a Day and confirmation about the warranty details
so far, its only two days, not sure about the electricity bill, once I get that, will update the same.
PROS: Good for 100 to 150 sqft room
Cons - connection pipes are not exactly 3M as advertised
