I think we give too much importance to advertisements and believe almost everything we see on TV or in print. Bisleri is something I have always had a problem with, it just never agrees with my system. Having no faith in Aquaguard or other forms of water filters, I decided to go in for Bisleri only to suffer from constant throat infections! It took me a long while to figure out that it was due to the Bisleri and as soon as I stopped drinking their water, I was fine! I went back to Bisleri just to make sure since they are such a reputed company and, sure enough, my throat infection was back with a vengeance. Thats when I stopped Bisleri completely. I have now switched to Hello Mineral water and am pleasantly surprised by their quality as well as their service. I think people who are thinking of going in for mineral water, should definitely consider Hello but stay away from Bisleri and play it safe!
