Product review (5 stars): It's a 2-for-1 deal, buy these and forget about it for a year!
So far it seems to be working just as well as the name brand 'Samsung' filters I've purchased in the past.  You basically get 2-for-1 if you buy these, had no problems at all.  Typically my 'reminder' light goes on about every 6-months, so these should keep me good for 1-yr.
