Product review (5 stars): Great product and vendor with excellent savings - so far!
The product is a 3rd party replacement for the LG brand filter. This one is priced about on-third the cost of the OEM but with the positive reviews so far I figured it was worth the try so I bought three (yes, I'm risk tolerant). The product arrived a day ahead of promised delivery date. My first response upon opening the package was that it seemed a lot lighter than the LG OEM part I had been buying. The lighter model is a little concerning - not sure why it was lighter since in my mind denseness of a filter  equates to more filtering material and better filtering and therfore heavier weight but I'm not a water filter expert and I've saved $30 so far. It installed just fine. I ran 8 or so full 12 ounce glasses of water through the filter to clear the black dust (carbon?) out of the new filter. It appeared clear after the 4th or 5th glass. I tasted it on the 9th glass and it tasted great ( full disclosure, St. Louis area water systems are already the best in the US, IMHO but it's nice to be sure these days). So far so good. I'll update this if anything changes my opinion but at this point this was a great purchase and I'll continue to purchase this brand and from this vendor.
