Ordered two of the LED light strips with 3M adhesive, 300 bright LEDs. The lights were really good but when I peeled the backing off the lights the adhesive was on the backing so no adhesive on the lights. The second set the adhesive stayed on the light. I cleaned the area with alcohol, wiped with water dampened towel and let dry. applied the lights and they worked great. The next they had started peeling off, put them back up and two hours later they started peeling off again. Returning the lights, ad says 3M adhesive, it is not.
