I bought aquaguard magna nxt on 10 oct 2017 by paying 18800 ₹ app. I bought it from eurekaforbes site. I was told before purchase that its best model with best technology. From day of installation I have been calling aqua guard to fix the problem, service engineer visited my place 4-5 times but failed to fix problem. Now I have initiated return of unit. After paying 18800₹app, I wasted my time in calling helpline, on top my parents didnt taste a drop of water.
