I think this product is so nice .so it sound is sweet, just like a jitar sound .if you use this product then you easily learn different type of work.because it is new modern era mobile and its version is more best than previous version .it mobile style is so beautiful and slim set .but it design is so beautiful because it design has come another country .i think it range is maximum twenty five thousand.but it price is more.it features is good like samsung j7 .it is more durable and lasting but it money value is not good.
