Product review (1 stars): 50% of the time, it works every time!
Purchased a 2-pack of these. Installed the first one per the instructions. I manage properties, and replace these regularly, so not my first rodeo with an in-refrigerator water filter. Everything seemed fine. Ran "3mins of water through the filter" just as the directions state. All good right? Nope. Come back an hour later, and there's water on the floor in front of the refrigerator. Open the door - every bin on the door is full of water. Ever seen ketchup floating in your fridge? I have. Ended up having to remove/clean/dry everything in the fridge - thankfully the wood floors weren't wet long enough to damage. All in all, about 3-4 gallons emptied in to my fridge. Couldn't tell for sure, but I think the collar below the o-ring was warped. I think it was a manufacturing error, not damage to the unit from shipping. O-rings were good. I installed the second one, worked (and is still working a week later) fine. So, about a 50% success rate with this product. If you do buy, make sure you keep an eye on filter as you are using in-door water on start up. If it has failed, you should see fairly steady drops coming from around filter.
