Buy it at your own risk and be ready to empty your pocket after 1 year of use.
I had purchased it from Vijay Sales, was good initially, but when I called for service they informed filter won’t be changed in first year, you can do it after 1 year.
This is because warranty period would be over after that time right ? Also they charge heavily compared to aqua guard for yearly AMC.
So it would be better to dump it and buy new aquaguard, if you are planning to user is for 4-5 yrs, your cost would be compensated.
