Product review (5 stars): Don't question yourself. Try this!
Although I thought this purchase was defective at first, I will say, it takes a few days to acclimate to your fridge. I have a Samsung 4 door (that's another review that I'm sure Samsung wouldn't appreciate) and after those first few days, it works perfectly. It was spewing the water out so fast and at times it spit in a continuous flow. It had a lot of air in it. Ive had this for almost 2 months now and while it has continued with serious pressure, it hasn't spit since it stopped 4 days after installed. I LOVE that we don't have to stand there like waiting for water to boil as we did with the Samsung recommended filter, when it needed to be changed 6 weeks after installed. This claims it doesn't need replacing for 12 months which I'm looking forward to confirming. In the meantime, I'm excited it still tastes fresh and still takes only 5 seconds to fill a 16 oz glass. BTW. We use it a lot. At least 4 times a week, I fill a 2 gallon pitcher on top of the daily use. I'm happy I didn't give up after the first few days and stuck it out. One of my favorite purchases.
