Let me start by saying this: Gorilla's Tough & Clear Double Sided Mounting Tape is NOT your average adhesive. I've put this stuff through the wringer, and here's the real deal.

The Good Stuff: This tape lives up to its 'heavy duty' claim. I mounted a 5-pound wall organizer in my garage (on textured drywall, no less), and it hasn't budged in three months - through temperature swings and accidental bumps. The clear finish is genuinely discreet; from just a few feet away, you'd never know there's tape holding things up.

Weather Warrior: Unlike cheaper alternatives I've tried, this survives outdoor conditions impressively. I used it to secure holiday lights along brick exterior walls last winter. After snow, rain, and wind, everything stayed perfectly in place until I decided to take them down.

Surface Versatility: From smooth kitchen tiles to rough concrete basement walls, this adhesive grips surprisingly well. It even worked on my textured bathroom tiles where other tapes failed miserably.

The Not-So-Good: Cutting this tape is an exercise in frustration. The adhesive is so strong that it clings to scissors like they're part of the project. Pro tip: Use sharp craft scissors and wipe them with rubbing alcohol between cuts.

Glass Woes: Like several reviewers noted, glass surfaces seem to be this tape's Achilles' heel. My car dashboard test ended with a melted mess (RIP Spider-Man bobblehead). For glass, I'd recommend specialty automotive tapes instead.

Removal Reality Check: When they say 'permanent,' they mean it. Removing items requires patience and possibly tools (that butter knife hack from another reviewer? Genius). But the clean removal without residue makes up for the effort.

Final Verdict: For most indoor heavy-duty mounting needs, this is my go-to tape now. Just don't expect miracles on glass surfaces or easy adjustments once things are stuck. At about $8 per roll, it's pricier than dollar store options but worth every penny for important projects where failure isn't an option.
