Is it advisable to invest in Unit Linked Pension Plans (India)?

There are various schemes from Insurance companies called ULIPs and Pension Plans. There is a general notion that the initial ‘allocation charges’ are fantastic: even upt to 100% of first annual premium. Hence my question is: is it still possible to make money after paying hefty charges to the companies? Is it possible to get income greater than bank FD interest rates? I would prefer answers from people who actually lost or gained.
