Product review (1 stars): You get what you pay for - junk
I always thought the brand-name LG filters were over-priced ripoffs. Man, was I wrong. There's something about the design or build of the Water Sentinel brand that seems like it's restricting the water pressure. Or something like that.

My LG refrigerator is a French door model, with an ice maker in the door. With this filter installed, it would plunk out two, maybe three, sets of ice per day. That's not enough, even for a household of just two people. The water dispenser stream - which isn't exactly Niagara Falls under normal conditions - was slower and weaker as well. I don't know if that's what was causing the ice maker troubles or not, but it's another bad sign.

I put in a proper LG filter and whattaya know - full ice maker all the time and happy water drinkers.

In other words, pay up. Get a discount on a two- or three-pack of real LG filters. They last roughly six months each, so make the investment. You'll be much happier in the end.
