Product review (4 stars): They seem to be great, we just got them
They seem to be great, we just got them, took a chance and ordered 3, one third the cost of the samsung replacement.  It fitted in directly and achieved a tight seal.  No leaking, which was an issue with some customers.  I gave it four stars as it has only been in a week.  At this point I would recommend the product.  May check back later when we have more experience with this filter.
