Used 3kg "value" pack to put up 3 prints under 1kg each. Followed instructions, cleaned wall, cleaned frame with Isocol. Adheared to frame using orange side of tape (as instructed). Came back after 90 mins to place on wall and nothing stuck! It came straight off the wall and straight off the frame! No stick at all! Waste of time and waste of money! And happened to have left over 3M Command strips to put up 1 and guess what?... It stuck! This so called product just sucks
