I have received my product on 19-10-2016 and I am using Jio sim also. Looking wise it is excellent and camera also good. Battery wise I give four stars. More value than your money. I am using one smart phone(since 2 years) and one tab(P480 since one year) manufactured by Micromax with out any problem. Any body can purchase micromax mobiles with out second thought. No even china phones are available for this cost. They are giving good products with low cost/prices. Hence, I strongly recommend the Micromax products as the customer/user of three products.
