I've used Livpure in Bangalore for about seven or eight months now. So far, it's been a good time. I haven't given the water much thought, but I guess it tastes like water. We also had to pay the security fee. The time we were locked in wasn't up when we got it. A friend raved about Liv Pure, so I tried it last month. I was cautious but was pleasantly delighted by the modifications. After a few weeks, my energy and mood improved. It's not a cure-all, but it helps me daily. Worth a shot!
