I started using using mcent browser when my friend told about it. It is the only browser which gives you free recharge for browsing. Yes you can also get free recharge for your mobile operator for browsing.
It is a very fast browser. It doesn't take time to load and is easy to use. You can surf the internet, read latest news, download and watch videos, do shopping and many more. It saves your data by using adblocker, text-only mode and smart downloading.
You can also enjoy the experience of incognito browsing. You can place home screen shortcuts. Now talking about recharge you need to make atleast 10000 points . 1000 points means 1 rupee. You can earn as many points as you want. You can redeem in form of datapack or talktime. You also get 1000 points for referring your friends.
So try mcent browser for smart browsing.
