Product review (3 stars): Product photo is misleading
1. Although the product description says in fine print "by Water Sentinel" the product photo seems to suggest it is made by GE with GE logo prominently displayed and all the GE models listed. When I purchased it, I was under the impression that I was getting a GE product. No. It is a generic replacement for the authentic item. If you are expecting a genuine GE item then skip this product.
2. The installation instructions were straightforward and if followed precisely work just fine. You have to make sure that the "O" ring provided is in place before you install it otherwise you'll get water leaks...more like torrents. They do provide an extra "O" ring just in case the one with the filter falls off or is not in place.
3. As for performance, after the initial air-bubbles cleared, it works as advertised. I can't tell any difference in water quality or taste than from the genuine GE filter. Since I just installed it today, I can't speak for the long term performance.
4. Unlike GE, it comes with a set of month stickers. You can either put one on the filter to indicate the month of installation or the month when the filter needs replacement (usually about 6 months later). On my refrigerator there is an indicator light that comes on when the filter is to be replaced. So I put the sticker to indicate the month of installation.

I just wish the product description was clearer on the manufacturer/distributer so that the purchaser won't feel deceived as I did. To me it is a matter of truth in advertising and the manufacturer's integrity. For this reason I only give it three stars.
