Product review (3 stars): Really inexpensive, but it seems to work--after a while
Here's your lede: Costs a fraction what the original filter costs.

That's 87.41% of the reason for buying this replacement filter for certain Kenmore and LG (and perhaps a couple more clone brand) refrigerators. It seems well made enough. Fits perfectly, but how would it sell in a sea of clone filters if it didn't?

If I had a minor complaint, it's that it takes a substantial runthrough of water to clear out extraneous carbon dust leftover from manufacturing, like 10 minutes of standing there like an idiot draining water out of your fridge's line, every once in a while splattered by dusky water when air blows through. Eventually, everything settles down, but you probably already ran three gallons through it before the water ran clear. That doesn't inspire the greatest confidence in the construction and attention to details inside the filter cartridge, but considering it's sealed, it's hard to know for sure.

The company's website looks a tad more polished than some competitor's sites, so perhaps that reflects in their filter products too.
