Better adhesive for LED light strips?
Strengthen the supplied sticky backing with something better at all stress points (beginning, end, change of direction, near any switches or other places the strip will be handled).
Options:

double sided foam tape
A bracket made of a strip of wood with wood glue and/or screws
A metal bracket ... just a thin strip of metal that runs across the light strip and is screwed into the underside of the cabinet tightly.
