Have thus just ten pictures (canvas 60x40cm) attached to the wall, each with 1x1 cm pieces in the corners. Holds perfectly and does not give the impression that they will ever fall off. From the canvas itself can remove the tape well, from the wallpaper as well, but it has a little color with replaced me with a glue dots of four - a testament to the good adhesive strength.
Update December / 14:
Did the Exodus are the pictures taken from the wall. Klebekraftwar very well - too well, in almost all splices was the color of the wall ... but well, the tape makes halt what it should: stick well. Therefore, no deduction, just a warning.
