I am obsessed. Great quality, says 3m on back. Fast shipping. Definitely would recommend and buy this product again.

No more carrying around my magnifier or phone and glasses. No more crashing of door sounds. They cushion the wood doors, and stop the wood against wood noise when they close.

The bumpers aren't crystal clear and the package i received is discolored. The end result is that the cabinet doors are held open about 1/8th of an inch which is very noticeable if you have flush mount cabinets.
