Product review (5 stars): Purchased for New Refrigerator
I purchased an LG Stainless Steel Fridge from Sears.  It notifies you via the LED lights on the door when it's time to replace the filter.  I received this notification 6 months after purchase.

Once I decided to actually replace the filter, a couple of months after I was notified, I went to Lowes to look for LG filters.  I went there because it's really close to my house.  Unfortunately, they were out of filters that would fit my appliance.  Therefore, I went back to Sears and requested an LG filter to fit my refrigerator and the sales lady assured me they had it.  She went and picked up one, said "this is it", rang it up and it cost approximately $75.00.  FYI, it was Kenmore brand.

Honestly, being given a different brand would have normally been ok, except 1) I was a little upset that it wasn't LG when she said they had it and 2) I felt it was expensive.  However, I took it home since I was already 2 months overdue with changing it and really had no reference as to how much these things should cost.

Before I opened the box, I decided to go online to seach for replacement filters and sure enough found them on Amazon.  LG brand.  About half the price of the one I had.  I decided I could wait another week or so to replace the old filter and ordered this one.  I of course returned the Kenmore.

Once my new filter arrived, I installed it pretty easily.  I removed the old filter, snapped this one in place and reset the filter notification LED (It took me a while to figure out how to reset it.  On my model, you have to press the notification icon for 3 seconds after installing a new filter.).

This filter works great (water flows as it should) and my water tastes good.  So I'm glad I checked online and very satisfied with this purchase.  And maybe most importantly, I didn't have to worry about "fit" as it was the exact same filter as my old one.
