Amazingly better for smooth plastics than the stronger gorilla (Super Glue, Epoxy) and UHU (Max Repair, Gel POR) while being cheaper. It takes the 48 hours it says (although the title here calls it "instant" - the product does not state that) to fully bond, but it sticks even transparent fabrics so strongly that the connection point is not a concern. The other glues under the same conditions do not hold at all. I had a construction that, after much research and expenses on its components, I thought it would fail due to a junction point. Luckily, this glue saved it. Just don't rush, let it bond for 48 hours. In my tests, it didn't matter if I rubbed the surfaces with sandpaper, it seems to hold just as well even on completely smooth soft plastic (which is the most difficult material for glues).
