I strongly suggest or recommend NOT to buy aquaguard enhance product. I bought it on 22 nd aug by mistake this junk prouduct. had lot of trouble to get it installed after 3 days . the product worked for 45mins and later it stopped working, called up customer care, escalated for repairing the brand new product. after calling more than 10 times the call center, logging on website, etc. nothing happened.later escalted with a service manager still the servicing of the brand new product was not done. now everyday I call the service manager to hear some excuse, without much luck of getting it repaired. almost 10 days have gone and I am not able to use the product. please think twice before subscribing for this terrible product and lousy customer support.
