I brought this geyser in last winter along with godrej washing machine so I managed its price for Rs.6500/-.it worked fine for 6 months, after that we start hearing that boiling sound and worried maybe its gonna explode.So I contact with the shop and they said thats not a problem, if ur too afraid ask our servicemen to come and take a look. this product comes with 1 yr guarantee, so I register my complaint and the company person come and he is alos said"this is not an issue ". But we are still confused and worried abt "do we need to remove it for our safety or just believe their words. Apart from that it works fine, within 10 min we get that hot water and it keeps that temperature level for around 5-6 hours .overall its a good product eventhough my suggestions is stay away from it coz nobody want to take risk about their safety .We all are buying things to reduce our workload and tension, what if a products become ur headache, once again am saying "stay away and be tension free "
