I am using this Smartphone since 6 months and it's very cool device as it's name "Coolpad".
Performance wise it's Awesome. It's 1.3 Ghrtz quad core processor and 3 GB RAM makes this device Awesome in performance.
It's 13 MP main camera and 5 MP front camera performance is also Awesome.
It's UI is also very cool and great to use.
I love this device.
