The major advantage of finvasia is zero brokerage. I have account with zerodha also but I use finvasia for intra day and futures trade which saves me 100-200 per day. Finvasia mobile platform is poor compared to Zerodha but It is manageable once gets used to. I am using finvasia for last one year and till now not faced any major issues. Some times their app freezes that can be solved by reopening the app.
