I purchased Kent RO with under sink unit first they forced me to buy an expensive AMC that doesnt cover consumables. The warranty for 2500 membrane is valid just for 3 months & AMC is valid only in the city done. They know there products suck as the 2500 membrane just died after 3 months.
No liability if parts not covered under AMC gone faulty due to service engineer mistake.
In Delhi AMC cost in 2500 including Parts( except consumable and water Tank though they charge extra 500 per year in AMC for tank model) in Hyderabad its just 2500 for visiting warranty .
So in nutshell they use all unfair trade practice to earn money
Highly expensive maintenance
Untrained resources in Gurgaon just 10 mins after servicing water bursted out from all directions of the RO ruining my modular kitchen and the saga continues in Hyderabad too as just after a few days of reinstallation RO came off the wall and they arent even sure which part goes under the sink and which should be fixed on the wall.
