Product review (1 stars): Not a good idea for an LG
This filter caused my LG refrigerator to malfunction!! I thought it was odd that all the controls stopped working correctly when I put it in; but I thought this was just terrible luck!! After troubleshooting with LG, and they said they never heard anything like it, they told me to call a service company that they would locate for me. But before I did this, and after my second call to LG and reseting the fridge three times.. I decided to put the old filter I still had back in, and reset it one more time. So I went to work and when I came home.. YAY! My refrigerator works fine again! This mistake could have cost me hundreds or even thousands of dollars being my refrigerator is now seven years old- as they probably would have told me to buy a new one! I usually always purchase a back up filter and at times more than one at a time as they offer better price for two or even three. Thirty days for credit is ridicules. I gave the company a chance to give my my money back and I give up. Maybe Amazon will, not sure, but  suggest buying a different one. By the way; I do not as a norm write a bad review.
Update: I did get partial credit and they did want me to return it, which I packaged in a ziplock as we all know it is full of water and it won't come out. I want to say that the one I got was the LG LT500P in case the others are fine. First time I ever had a problem with one. I suggest just stay with those that you know work. It isn't worth the trouble.
