Product review (4 stars): Good filter.  Missing larger "outer" gasket?
Shipped quickly, but I don't think it was packaged very well by the seller (Deepdiscountco).  They came in a plastic envelope, but there was no padding, so the boxes were beat up pretty well.  The filters seemed to work well, but they were missing the larger "outer" gasket, but I used the gasket from the old filter.  They did come with the smaller "inner" gasket.  I suspect you want both, to avoid leaking.  I thought the foil seal over the filter opening was a nice touch.

As it stands one week out, I would buy this filter again, but I might choose another seller.  Water tastes better and there was not much carbon fine leakage into the water, and that flushed out quickly.  I will update this review when I need to replace the filter, to reflect how long the filter lasts.
