Had to find other fitting to make connection . There is no change in the water taste . We have hard water here and the water still taste like slime not crisp and clear like I was expecting . Thinking of asking about return . Just don’t feel like going through the trouble of taking it out and shipping .
Cons: Cloudy Water
No, I would not recommend this to a friend.

I am totally frustrated

I bought this under sink filtering system with the hopes of replacing the sink faucet and pitcher products previously used.
So far, it worked for a brief period of time then slowed down to a trickle. Got instructions with two things to try. Tried backing off filters 1/4" and it worked for a brief period of time then slowed down to a trickle and stopped. Tried inserting a coin under each filter. It worked for a day and then the same slow down, stop, intermittent slow flow.
I have spent literally hours on this filter only to arrive at the same disappointing conclusion. I could not recommend this product at this point and am runnoing out of patience. I have had reverse osmosis units in the past and a variety of other brands but none have had this problem. It certainly is not the installation and I am at a loss to know what to try next.
Cons: Slow pour

I liked the price point on this item. Also liked the fact that it says it retains minerals. However I am not sure how I can test that. I had difficulty with locating parts since my faucet is 1/2" not the 1/4" fittings that come with it. I have never seen a kitchen faucet with 1/4". So I had to spend an addition 15$ on adaption parts.
Its been two weeks plus since I have installed this. I use this for my cooking and coffee, tea water. I tried it for just drinking after one week. Not sold on taste. Couldn't even drink a glass. Will try again this week, hoping it will taste good since I really want to stop hauling my water jugs back and forth to the water machine.....
Pros: Easy to install

Service was good. Not happy with barrage of email, and I have opted out several times. I see I need to contact directly and insist a little more firmly. Installation is very easy, and I would say requires minimal skill. Not sure I taste much difference between the filtered and tap water. Either it's not really doing anything, or my tap water isn't that bad to begin with and did not really need it.
Only reason I bought an under counter is we upgraded counters and faucet, and could not use the Brita faucet mount anymore.
I bought the more expensive high flow, and without a comparison to regular I can't really tell if worth it, but I anticipated higher rate of flow.
Pros: Nice faucet
I would recommend this to a friend!

Pink slime in faucet outlet
on October 23, 2018

Purchased the 3 stage high volume drinking water system. After the initial installation I used it for about 4 months. One morning I was getting some water in a to go container and I noticed a pink slime hanging out of the end of the faucet. This was real concerning considering this filter states it removes chemicals and bacteria. Needless to say I have not used it from that point. I’m not sure what causes the pink slime, but after reading some about it I’m not comfortable continuing to use it for drinking water.
Pros: Good Water Flow, Nice faucet, Easy to install
No, I would not recommend this to a friend.

My husband installed this easily. There is a big difference in the water taste. We bought this to filter PFAS which is a very dangerous contaminant.
Pros: Easy to clean, No odor, Clean taste, Long lasting filter, Good Water Flow, Durable, Nice faucet, Easy to install
I would recommend this to a friend!
