Product review (1 stars): NEVER buy this water filter from Amazon.com!!!
We bought a "LG 5231JA2006A Refrigerator Water Filter" for the icemaker and water tap in our LG frig.  We bought it in June but since we were going away for a few weeks to visit relatives, I figured I would install it when we returned in late July.  After installing it, I ran the water through it as per the instructions.  The water tasted terrible!!!  I figured that I would keep flushing it and make a few containers of ice.  The taste got worse!!!  I removed the filter and the water actually tastes better.  And since I waited too long to install it i will only get a partial refund AND I'll have to pay the shipping charge to send this piece of junk back.  FORGET IT - into the trash it goes!

Lesson Learned - this isn't the first time I have bought something from Amazon.com that was defective - but it will sure be the last.  I saved a few sense and lost several dollars.  NEVER AGAIN!!!
