Product review (4 stars): It went into the slot fine, but was extremely hard to turn
Purchased for a Kitchen Aid side by side refrigerator that was in the home my daughter just bought. Previous owner had not put a filter in, so we were guessing on the model number. It went into the slot fine, but was extremely hard to turn, and took both of us taking turns twisting. That may be because no filter had been in it for a long time. It finally turned into the right position, and we flushed about a gallon and half of water out of the dispenser. Be prepared for some sputtering, as the air in the filter gets pushed out. Water now tastes good. If this filter performs well for the next 6 months, we will order again. I only gave it 4 stars because it was so hard to turn when installing, and I'm a little worried that it may be difficult to remove at replacement time.
