Product review (1 stars): INCOMPATIBLE WITH OLDER MAYTAGS
Do not buy this if your Maytag Refrigerator is older than a 2014 model!!!

I have previously used this product and been very happy with it.  But when I ordered a replacement, it wouldn't work at all.  I ended up calling their 800 number, where I was informed that a "redesign" of their filter means that it won't work in Maytag's older than last year (2014).  I asked why they were selling it as "compatible" with Maytag if it was limited in its use and I was told they could offer me a "work around" by "forcing a hardware reset".  As he explained further, I would have to force the old filter as far counter clockwise as I could before pulling it out, turning "hard, but not too hard".  When I asked if this could break anything in my refrigerator, he said they couldn't be responsible for any breakage.  When I asked why they didn't change their packing as this clearly is no longer compatible with older Maytags, he would only say he could offer me guidelines around the problem.  Without guarantees.  Very disappointing from both a product and company point of view.  Ended up being a waste of time.
