Man does this stuff stick! Love it

Great tape

Not as strong as it needs to be on painted concrete walls like in my classroom. Still doesn’t always keep light framed posters up

Strong and durable. I used it with small wood strips for extra rack support in my closet.

Bought this to mount a lightweight magnet to support a couple of small knives (less than 10 lbs total according to my kitchen scale). The magnet is 12" long.Ran a strip of tape the entire length of the magnet, cleaned the wall, and pealed off the backing paper and mounted this to the wall. Less than a month later it fell off. Tape that was pressed onto the wall is completely dry and non-sticky.

Very good product.

Could not even hold a guitar on the wall...
