Product review (4 stars): LG Refrigerator Water Filter
The water filter works very well and I can say that I am very pleased w/ the product.  My complaints are minor:
1.) To search for this item is difficult because the number LT700P doesn't appear on it anywhere.  I was able to blow up the pic to see the long reference number matched mine.
2.) Very difficult to pull out of the clip in the fridge.  I wasn't sure if I was doing the install correctly because I had to pull so hard on the old one but it all worked out.
3.) The filter is asked to be replaced so quickly and being a single person using this item, I know it doesn't get used up in the few months that is stated.  I use for a year and my water is just fine.

All in all, I like the product and my water tastes good and works well for my Keurig so I'm very satisfied.
