majorinda 4 Amazing that it works so well, it was also easy to apply, since it had a plastic film backing. We have used small leftover pieces to hold remote controls for the Air Conditioner on the walls. One did fall down in the room above our bedroom to wake me up but it was because we used a tiny piece (1 cm) and the back wasn't clean enough (the tape cleaned it!). We also use it with 3M hooks outdoors on the rough stucco-style wall to hold up a garden net for vines to grow on. Only one of the five hooks had issues and kept falling off in the last few months, rain or shine. We tried another version (https://www.amazon.co.jp/gp/aw/d/B0813D6V8V?psc=1&ref=ppx_pop_mob_b_asin_image) that was cheaper, but it wasn't as easy to use since it stretches as you unroll it and becomes longer than the plastic backing film and thus difficult to apply as a result.
