This is very very bad product. I have bought it on 30th December 2017. And installed it on 2nd January 2018. After that it is continually arising problem. The technicians are just horrible illiterate. They don’t know what is the basic features of the geyser. Everytime a technician came and make the condition more horrible. Don’t buy it . This is a worst in fact more more bad than worst product. Fade up with usha. Hate it usha just hate you. Cheater company. This should be given minus 1000 star.
