I have good experience with the vivo company because I bought my first Android mobile vivo y51L it's awesome Mobile , in this mobile every feature advance with one problem in this mobile that a is the weight of this Mobile too much heavy. And in looking wise big phone just like China mobile.
Network coverage also good in any where we can use this mobile.
Vivo mobile company customer service also best as compared to other companies and mobile cost not to much everyone can buy this Mobil easly.
