Product review (3 stars): Check before you cut.
Could have been 5 stars. I always follow instructions to a tee. So I cut the "fill tube with foil" to the exact size of the given template for my refrigerator(M). Guess what, the template was wrong! After many calls and hours on the phone, GE first sent me the wrong part and then reluctantly sent me the right part after I figured out the part nunber. Their parts system did not show the fill tube as being part of the IM-6 kit, so it was hell to get them to send it to me. Anyway, check before you cut.
