Product review (4 stars): Questionable Warranty
Out of the three we received, 2 worked and 1 leaks.  I understand that things happen and am not upset that we got one bad one. What does confuse  me is that, from what I can see, the only warranty you have is a 30-day money-back guarantee.  So when you buy the 3-pack, unless you have 3 refrigerators that all use this filter, the only one that has a warranty is the very first one you install since you won't use the other 2 within that period.

I've looked and cannot find any mention of warranty other than the 30-day return.

I am not unhappy with the product.  Product failures happen.  It just seems to me that putting 3 of these into one package with a 30-day warranty seems odd.

Update:  I changed to rating from 2 to 4.  The re-seller responded to our concern and replaced the defective filter even though it was long out of warranty. I really appreciate that.

I still question how buyers can actually utilize the warranty for the package of 3 within 30 days.

Others have mentioned they can taste the difference between LG's filter and these.  Our taste buds are not that sensitive. Water run through these filters taste just fine to us.
