Manufacturing Defect- Terrible
on September 16, 2017

Verified Purchase:Yes
Extremely slow water flow. Very difficult to install canisters. Spent a few hundred dollars to have a plumber install it. Now I have to pay him again to remove the system. Should pay for my plumbing costs!
Cons: Slow pour, Difficult to install
No, I would not recommend this to a friend.

forces filter replacement, so wasteful
on January 11, 2020
Posted by: chase lang
from ca
Installed in 2018 and did not realize there is no way to avoid replacement of filters before they are used. 2 people part time do not use the same amount of water as a family of 4. no way to adjust. Also periodically starts leaking
Pros: Easy to install
Cons: Filters need replacing too often, Not durable
No, I would not recommend this to a friend.

Just okay
on February 7, 2018

Verified Purchase:Yes
We have highly chlorinated water. It smells like water from a swimming pool. The 3 stage filter seems to be okay but the water from my refrigerator with its single little filter tastes better. It makes me wonder if the carbon is doing very much to remove the chlorine smell and taste.
No, I would not recommend this to a friend.

I have never detested an item so much
on May 27, 2024
Posted by: LJC2
from Baltimore, MD
It's hard to believe how much I hate this thing. The destruction to my home, the constant problems and lack of functionality. I have no idea why I continue to try, because it doesn't seem worth it, I just wish it could serve the purpose I thought it would serve (reliably produce filtered water). There is a delicate connection from the water line to the system and if you so much as breathe near it, it will come loose and flood. Christmas Eve 2022 was spent in my basement with a shop vac all night, as my entire kitchen and basement flooded because of this thing. I had plumbers come three times to fix the connection and finally the third time they put in their own that was sturdy. Great. November 2023 my replacement filters come and the water just dribbles out of the faucet. I uninstall and reinstall them a half dozen times; nothing. I let it sit for six months because I'm just so frustrated at this point; I google this issue and there is a reddit thread about how this is a KNOWN ISSUE and to put a quarter in the bottom of the pre-filter casing. It worked. CAN YOU BELIEVE I DIDN'T USE THIS FOR SIX MONTHS BECAUSE THEY KNOWINGLY SEND FAULTY EQUIPMENT AND CHARGE YOU FOR IT AND I HAD TO PUT A QUARTER IN FOR IT TO WORK. So my latest replacement filters come and I cannot for the life of me unscrew the third filter. It has become such that I have so much anxiety every time I have to deal with this thing that I just avoid it and I have just been using a Brita pitcher for the last 6 months. I have never bought something so consistently problematic as this system. I hate it so much and would like reliable recommendations for a better company.
Cons: Slow pour, Difficult to install, Not durable
No, I would not recommend this to a friend.
