Review on 1-Roll of 3/4-in by 66-ft Scotch Electrical Tape in Black for Improved SEO by Bryan Sperling

I can't believe this is a 3M product! After a few days there is no stickiness, just a slimy black film. I tried many places and uses, it had nothing to do with heat or humidity (room is not controlled, never exceeds 76F or 52% humidity). The attached photo of the charging cable shows the film that is left on it and how it doesn't stick to itself or the cable. Leaves a terrible residue that peels off anything it touches, including fingers (see photo). The tape doesn't even stick to itself! I will never buy 3M products online again.
