I've only used one so far and it's been good. I don't care for the additional step of having to soak it prior to install. It's either for a few hours or overnight either way caught me off guard!

3/24/18 Update!!!
Today my water stop dispensing from the fridge. I made sure all doors are closed, the control panel was not locked and the water connection from the sink was fine. Checked the filter and no leak. Took out the filter tried the water and it worked. Put the filter back on and the water stopped. Looked at the instructions and they said to soak it again for 15 minutes...could just be air in the line or something. Tried it and nothing. Soaked it an additional 30 mins and nothing.
Opened a brand new filter soaked it for 15 minutes put it in and it worked!!! Wth? This is my first experience using an off-brand filter and it just stopped working. Could that mean it's full of whatever it's supposed to stop and can't filter any longer? I don't know;however,  I do know when, I've used Maytag brand filters even when it should have been changed it has never stopped working. So I didn't get the 6 months, I got maybe a little bit over 3. Not too sure what to think.
