Okay, so I was skeptical at first but this double-sided tape is LEGIT. I used it to hang some solar lamps on my cement block wall - been up for weeks through rain and wind! No drilling, no fuss.
The adhesive strength is insane. Like, I accidentally stuck two metal parts together and now they're basically married. Had to use a hairdryer to separate them when I messed up the alignment (pro tip: measure twice!).
Worked perfectly for my picture frames too - no more crooked family photos! Though fair warning: doesn't play nice with glass surfaces from what other reviewers say.
Only complaint? The roll ends with about 6 inches taped to cardboard which feels kinda cheap. But considering how strong this stuff is, I'll let it slide. Definitely buying again!
