Product review (5 stars): very easy to install, fixed my slow water dispenser problem
The new replacement filters do not fit the original refrigerator filter heads properly, which causes the water the dispense very slowly.  Well, after swapping out the filter head with this one, the new replacement filters works perfectly now.  I think it probably took me about 10-15 minutes to install.  If you had the same problem as me, then don't be scared to change the filter head to fix your problem.
