I have purchased vivo y66 last month and I am quite satisfied.It has large screen and picture clarity. Its music is mind-blowing as the sound quality is better than its other equivalents. Containing 3GB RAM and vast screen, it becomes a clear choice for gamers and the people who love everything on their smart phone. The expandable memory is huge which compensates for a memory card. Camera is superb. 13 MP rear camera and 16 MP front camera is enough to make it a better gadget under 17000.Stylish look, good user interface and slim design makes it a must buy.
So I would recommend this as a best value for money product.
