This whirlpool purasense 7L RO. Is very useful for those who have a budget to buy this. In my case I have enough money to buy this and it seems to be good. It is working properly even four years latter today.
But in case you are going over budget for this whirlpool purasense 7L RO then you should not have to purchased because I will rate this 2/5 on the basis of value for me. It has stopped working two times and that was the major concern but after a repairing it started working properly.
See your budget and then make a final decision.
