Product review (2 stars): Supplier, check the part for the loose metal gasket before shipping!
Arrived without the metal spring/gasket for the mounting screws.  The original are a different size, so had to make one.  The supplier is most likely only responsible for not checking the part before shipping.  As for Samsung, why use a plastic bracket over a gas flame?  Especially as the largest, hottest flame is on the right side of a gas stove?  Electric stove, no problem.  The gasket snapped out OK.  But, how does one live without jewelers tools?
