Product review (1 stars): Poor quality and fit, leaks!!!
The first cartridge I tried would not lock into place no matter how hard I tried and leaked.  Thinking it was a one time defect, I tried another and it had exactly the same problem. Just to make sure I wasn't doing something wrong, I then tried a genuine Samsung cartridge which easily locked into place without leaking.  Clearly this is an inferior product that is not manufactured to the same specifications as are the Samsung cartridges.  Fortunately Amazon has a superb return policy, so in the end all it cost me is a little time and a great deal of aggravation.
