I have used this phone. And it has very amazing function .the lava iris x1 is among the top contenders.with the similar price tag and offering better features on paper.imagine the iphone 4S made with low cost materials and you have the lava iris X1 on your hand . the front and back are completely flat, while the sides have crome band going all around.And the touch of screen is very senstive And Very atractive slim shape and also this phone has very afordable price to everyone. My suggestion is everyone must buy this phone to experiance latest technology.
