Product review (1 stars): defect merchandise not working !
This time I received with double plastic ring (black) on the neck and I am not able to insert into the refrigerator.
I never had this problem before...See picture. On right side of the pcitures is the orginal and a left side is the new ordered with the two plastic rings which cause the problem.
Shipping is extremely slow I received 13 days later after I  purchased.
