Product review (1 stars): GXRLQR has design flaw!
Do not buy as a replacement filter for your under the sink GE filter system.
It fits and locks, but the two plastic nibbles inside are not in the correct place, they are displaced 90 degrees so the valve is not opened when twisted and locked in place.
Don't know why GE created a different filter with identical part number GXRLQR, shape and color?
I bought four (4), not happy now.
