Unfortunately, the main line leaked from the water input and after 3 install and uninstalls, I had to return the system. I was bummed because I really liked the water system.
Cons: Not a sound product
No, I would not recommend this to a friend.

I'm disappointed the item. I just installed it in late Sept and found that there was so much scale after water boil! I had to use my previous water filter pot after.

A great unit to replace my old one

Verified Purchase:Yes
I needed to replace my outdated 2-stage GE filter which served under our kitchen sink for decades. Found this Aquasana Max Flow 3-stage to be a very nice replacement. It quite nearly fit the exact measurements of the outgoing one. Would recommend this particular model over the shorter cannister ones because of its faster flow capability.
Pros: Clean taste, Easy to install
I would recommend this to a friend!

Great purchase.

This filter checks all the boxes. It is well made, installation by a professional was fast and easy. Water tastes great. I chose the filter because of it's broad coverage of contaminants. I combined it with an epic nano pitcher that takes care of micro-plastics in addition to what the under sink filter provides.
Pros: Clean taste, Good Water Flow, Easy to install
I would recommend this to a friend!

Exceeded Our Expectations

We've had The RO about 3 weeks now and we LOVE IT !! I wish we had ordered one sooner. My husband had no problem installing it, the longest process was drilling a hole in the sink as per our sink wasn't adapted for a water feature. I like the idea of setting up a starship for new filters so I dont have to remember when to order. The Quality of the water is supreme, my whole family has felt various health benefits. From a decrease in inflammation, weigh loss, cleared up acne and taste buds for certain foods are more enlightened. Definitely give the Auqasana a 5 star rating.☆☆☆☆☆
Pros: Easy to clean, Clean taste, Long lasting filter, Durable, Easy to install
I would recommend this to a friend!

Unit failed and flooded my kitchen and basement
on January 16, 2018
Posted by: Ram L
from New York
Unit worked for two weeks and then the tube connecting the unit to brass t broke in the middle of the night. Pretty much it flooded my kitchen and basement. Spend a day dumping the water out. I got a plumber to install the unit and he did it by the instruction book. Not sure how the tube came off the the brass T connector.
Cons: Slow pour, Not durable
No, I would not recommend this to a friend.
