Product review (4 stars): Better filters than HDX, one unit defective.
The first filter out of the 3-pack I attempted to install would not fit. I called Samsung and they said I must use force, but never before was so much force required to install one. I gave up on it and grabbed the second filter and it installed using moderate amount of force. The first had to be a defective unit. Other than that, better filters than the HDX. These don't drip water like the HDX, nor do I have to drain them as long to eliminate all the air.
I used the HDX brand for the last 2 years, but decided to go back to Samsung originals as I was tired of the leaking water which was staining the stainless steel.
