Transparent Wall Hooks Adhesive for Kitchen Bathroom Bedroom Office and Over Door Damage Free Heavy Duty Waterproof and Oilproof No Scratch Reusable (4 pcs)

I thought Fealkira is better. Seriously, a single Fealkira adhesive hook rated at 13lbs on a flat surface held a heavy Christmas wreath (>20lbs) on a corrugated (yes, wavy) ceramic tile wall for 8 weeks without fail. This one did not even hold a light wall art <10lbs for 10 hours.

using these to hold up my dogs' collection of harnesses, collars, and leashes and they're holding up very well, even with a lazy job of cleaning the surface. I like that they're reusable and they look better than the 3M sticky hooks that I used before, but aren't as strong. Each one is holding up less than a pound so these were well worth it.
