Bought this to mount a magnetic knife holder and expensive knives. Used 22" to hold 2.2lbs. Mounted on white ceramic clean tiles. Held for 1 day and then came crashing down. Not impressed!
I am a little disappointed with this. I used other brands before and this is the worse one so far. It doesn't stick strongly, definitely is not for heavy duty at all. I just used it to hold a pair of desktop speakers on the wall (not heavy at all) and they keep falling.
I purchased this tape to hold my door size mirrors up. It works really good. And is very sturdy
