Like many other reviews on here - poor experience. Only give 2 stars because I "eventually" got my money back.
Bought a samsung filter which turned out to be an issue, see this Samsung link and specifically the review that explains the problem - Fridge Filters did not know about this. http://www.samsung.com/uk/consumer/home-appliances/refrigeration/filters/HAFIN2/EXP
When the filter did not fit, Fridefiltershop.com communication was slow and unclear, they never answered the telephone and I sent numerous emails.
Only after I threatened to escalate to trading standards, I eventually got a reply and then it took a few weeks more to finally get my money back. It seems they try to avoid the issue.
I will not be buying from this company again. Used Amazon instead and one from "finerfilters" instead, the product fitted and it clearly shows its a compatible product and resolves the problem.
