This has been a no-problem filter. Once you get the system installed, it's a piece of cake to do filter changes. Just remember to turn off the water first! The RC-EZ-3 filter will also fit this housing, and costs less, but it does not offer the performance of the EZ-4. I've been sticking with this model. Very happy with performance. Expect a lower water flow rate than your standard faucet. Important note: if you use a SEPARATE faucet assembly for your filtered water, you need to pay attention to where the water exits the tip. It WILL after a while grow fungus and bacteria where the water exits, because this filter removes the chlorine that would help prevent that. About once a month I take a small amount of bleach and mix with water ( one part bleach, three parts water) and fill a small cup or glass with this about halfway. After blotting the end of the faucet dry, I lift the cup up to cover the end of the spout, so the tip is submerged in the bleach mix (see pic). I hold the cup there about ten seconds or so, then remove it. Let it alone for about ten minutes, then just run some water for ten seconds or so to flush out the end.

great filter easy to install, works perfectly. TIP: I called culligan, you do not have to change the filter until the water flow slows. the blinking light is just a timer that acts a reminder (we remove the battery on ours). Our filters last over a year.

Great filter until it leaked about 4 months of use the plastic housing cracked. Spraying water everywere. Thankfully we were home to manually Shut the valve off

Update: 5/2/2013

I have a subzero Refrig with no built in water filtration. This was the best option I could find.

I have changed 6 of these over the past 3 years at about 4 month intervals.

3 have exploded. Forcing me to install an automatic water detecting shut of valve at my water valve that splits to my refrigerator...

We have had this unit for about a year and a half and have carefully replaced the filters four times. We initially loved the "easy snap in" change and all was well - the 4 level filter seems to do a great job and we didn't notice much restriction; each lasted about 5 months. This week's replacement was different, though - we woke up to a HUGE flood in our kitchen with a ton of damage. Came back here and saw a number of other people have had the same problem. I can't quite see if it's the main part or the filter, but it sounds like it might be a breakdown of the base (although we don't see any cracks, but can see the leaks and drips all around the top part.) This should not be happening after only a year and a half.

Has anyone contacted Culligan? I have emailed them and will update this review if I hear back.

This is a good filter but it constantly leaks. I've changed the filter head and the filters themselves several times and it still leaks.

This is my second purchase bc the the first started leaking around the gasket part in the head where you attach the filter. This happened after 5 years which I guess is a decent amount of time. I'm not surprise bc propably all the twisting and untwising when you change filters causes the little o rings to warp eventually. If I had to do it over I would try to mount the head near the cabinet door if you have that option. It's hard trying to twist it on when it's tucked in the back of the cabinet and you have to crawl under the sink.

This is a decent filter for the money but it isn't the easiest install because the white plastic 3 way adapter that comes with it doesn't fit most water lines. You will need to buy a 3 way adapter 3/8 in by 3/8 in by 1/4 inch with push pin type outlet on the 1/4 inch perpendicular part of the adapter. I wish I had known this and saved myself a trip to Lowe's. I was told by my handyman that it's better to use a brass adapter bc it is less likely to crack and leak over time. You will have to buy a separate push pin adapter if you can't find a 3 way one that already incorporates it in. Not a biggie but does take a bit of wedging it in to get it into the 1/4 inch plastic tubing. I used a bit of Pam cooking spray to wedge it in. See photo. If you can't find a brass one heres an example of a plastic one.

My tap water reeks of chloramine, and these filters allow us to drink, water our pets, and cook without having to schlep 5 gallon jugs back and forth to the grocery store. It's been several years now, with no leaks. A washcloth placed under the filter catches the dribble when I change them out.
