Product review (5 stars): A comparable product to OEM, installation easy, good fit, very good value, beware of authenticity from poor comments
I researched hard and tried to justified buying OEM brand like my original LG filter (5231JA2002A) - afterall, its water I drink from everyday, why would i skim on the price- even if the original cost twice much right? But after looking at many manufacturers' websites (some even created blogs to explain why they are just as good as OEM) and reading many reviews - including the bad ones, i choose to take a chance.

My experience:
Just installed - very easy, took less than 30 sec to pop it in. Not a drop of water spilled. Clear instructions on paper.same thing like what everyone said - must run through and discard the initial couple of gallons of water to clear the carbon residue inside the filter.

I used to live and work in developing nations where water sources is very questionable. Almost everyone, foreigners and locals, who could afford it (generic ones cost about US$15 for complete pack of 3) would have one of those triple water filtration system under their kitchen sink - we changed ours every 4 months despite package recommended 6-8 months (and if i delayed changing, i will cry when i see the state of the disgusting dirty filters and regret big time).

Here in the US, compared to the rest of the world, there are so many regulatory boards that impose strict standards on treatment plants, water pipes, sampling tests etc ( my partner is a water engineer so i hear non stop of this).  If you are in an area that uses well water or you think has higher pollutant, you could add the triple filtration system under your sink and link that filtered water through a hose to your water filter in your fridge but it is really not necessary for most households in US.

After i found installation, fit, and the flushing part all normal, i began to wonder why the existence of many of those negative comments. It disturbs me to suspect fake reviews/paid competitor reviews to degrade a product so as to confuse and dissuade potential customers.  I am so glad to receive Amazon's latest news (yesterday, Nov 10, 2016) on them stepping up to tighten regulations against such unethical practices so as to maintain a useful and informative platform for genuine users for the Amazon community.
