Product review (5 stars): A 30 second job
The GE instruction sheet was incorrect, there's no adapter on top of the MSWF filter which needs removing. Just peel off the tin foil cover on the top of the filter, fill the new filter to the top with tap water and screw it in the holder in the refrig. Drew off two large glasses of water and by then the "sputtering"  had stopped and I was back in operation. Last thing to do was resetting the red "replace filter" LED warning light.

Literally took 30 seconds and didn't spill a single drop of water although I had put a dishcloth under the old filter before I removed it based on some other folks claiming they got water all over the inside of their refrig. Obviously user error. When the old filter is unscrewed, a check valve shuts off the water supply to the filter. I think the folks with problems pushed up on the new filter when trying to screw it in; thus, unseating the check valve and spraying water inside their refrig. Don't do that...just let the threads on the filter do the work as you screw it in the mount.

Amazon's price was competitive with other discounters, shipping was free and I received the filter in five days.

What's not to like about the Amazon ordering process? Absolutely nothing!

The old filter lasted 10 months (family of three) and I just put an alert in my computer to order a new filter in nine months so I'll have one on hand the next time.
