First of all it is the most affordable smartphone I ever seen under 7K. It comes with good specifications. It is an indian brand which makes me happy too. I bought this phone because I love installing custom rom on my device. Ther are plenty of custom rom for this device. The sound reception is good I say excellent. Very easy to use. Comes with 5.5inch 1080p HD display which looks very crispy and very bright. It is a durable smartphone, And is more than value for money. If you wanna buy a budget smartphone under 7k go for it it will never let you down. But keep in mind there are two variants available one with kitkat(Android 4.4.4) and another with lollipop(5.1.1) which comes with VOLTE support(using Jio 4G sim And can make calls) but Lollipo variant comes with locked bootloader so u can’t install custom roms(as of now the developers are working on it hope for the best) but kitkat variant comes with unlockable bootloader( No VOLTE) .So buy according to what you need.
