Product review (5 stars): Good product!
I was a bit skeptical about this, since I had been paying $50 for the official filter at my Sears store, but was glad to find this Waterdrop product.  It is reasonably priced, fit nicely in my Maytag fridge and seems to work well.  Haven't been using it a long time, but it seems no different from the outrageously priced versions. I am glad I found this product.
