Product review (1 stars): Totally Unacceptable Performance!
I can only think of one word to describe this product: Garbage!

I ordered the two pack and installed the first one on Nov. 15 and, I flushed about two gallons of water before drinking any. At first, the water tasted a little different from what we were used to from the other filters we've used (LG, Refresh, GE). But, in about three weeks, the water started to taste funny. At first, it had a kind of a tart taste. A few days later, it became a more defined metal taste. And, for the last week, the water started to taste like rusty metal and became undrinkable! And, all of that, in spite of us having an external, in-line GE filter as well, which I left in place from our old refrigerator and I replaced that filter less than two months ago!

Even with two children at home and hot summers, these filters would easily last us 5-6 months. Now, there's just the two of us and, this Waterdrop filter's gone funny on us in less than a month? Unacceptable!

I just installed the second Waterdrop, hoping it provides us with a few days of drinking water until we can get a REAL filter to replace it with. Truth be told, I wouldn't even bother with the internal filters if there was a way of by-passing them. The external, in-line GEs always worked great for us.

Lesson learned! You get what you pay for! This is a completely unacceptable performance from Waterdrop!
