Product review (1 stars): Money down the drain...
Each canister lasted about a month before change was again necessary.  Unlike prior versions, upon expiring, these began to dispense foul tasting water.  No joke - I filled a cup of water, stood at fridge, consumed, filled second cup and could not drink because of strange flavor.  With previous versions I was able to continue to use filter despite "change filter" reminder.  Had been ordering LG LT700P which worked properly.  Tried to save a few bucks and got burned.  Filters are expensive, no doubt.  But even the LG at around $30 is half of what similar product would cost at Sears.
