I decided to fit zero b emerald because the appliance was slim and it would fit easily into the space where I had my most horrible Aquagard iNova water purifier. Also, this model was an RO model which we very badly needed as our building was getting only bore well water. The sales person I spoke to was very proactive and patient and worked very hard, even on a Sunday! Within half an hour of my calling he was at my doorstep and proceeded to give an impressive demo.
He also checked that the model would fit into the space where my old Aquagard was. He took the cheque and early next day, Monday, he was back at 9 am with the new model! Very efficient! But the guy who came to install the machine was not all that good. He did a just about ok job in fitting the unit, but did not fit the tank properly and we found after he left that the tank was leaking and that the drainage tube kept coming apart due to the high pressure.
The drainage tube problem was easily fixed using insulation tape by myself, but the tank kept leaking and service guys were called ho said that the tank washer had been bent during fitting! It was not possible to change only the washer, so some PTFE tape had to be used. Now the unit is working well and giving us good, pure and tasty water.
Ladies will like this model because it looks good in the kitchen. I recommend this unit for families
