Durable, sturdy great water taste!

I have bought many faucet filters this is the well made and durable. Water flow is much better than other brands, good tasting water. Now time will tell.

Super easy to install and improve TDS test result

Easy installation, and great a measurement for the TDS, around 130 from 200 on the regular tap water. Happy with the purchase!

No Leaks or Bubbling

We originally purchased the model with the push-button switch about a year ago and no matter how much plumbers table was used or tightening of mounts, there was always water bubbling up from around the mounting adapter. Annoying, but we continued to use it until we moved.

After moving into our new place we decided to replace the filter cartridge, but looking at prices ($32.99 for 3), we decided to just purchase a new unit. I��m in agreement with the reviewer on cleaning the cartridge area on a regular basis. Ours had sediment & other disgusting looking sludge around the fittings. Yuck!

The unit with the manual flip-type switch went on with a breeze and there were no leaks or bubbles whatsoever. Didn��t have to use any of the colored adaptors, just a little of the plumbers tape (included) to install and it worked perfectly. Besides, the chrome mounting adapter maintained the aesthetics of the unit.

So, from our experiences, we would highly recommend this particular model.

Really like

I really like this filter system, swivel, level does not hinder sink access.

The water drop filter is easy to install.

It took me approximately 5 minutes from start to finish to install the filter. I've brewed my first cup of coffee through my Keurig machine and it tastes great. I'll update my review once I've had the filter for awhile.
