This is the best PE adhesive that I have ever used. It works as advertised. However, the application system is a train wreck. The applicator tube isn't securely attached to the screw-on cap and is constantly falling out of the purple plastic piece whenever you remove the needle used to open and/or clean out the applicator tube. I finally had to superglue the tube into the screw-on cap. In addition, if you push the cleaning needle in too far and leave it there for a few hours the glue will set inside the tube and make removal of the needle impossible. No amount of fiddling will free it, period. Your only option is to throw the cap out and put on a replacement applicator tube, which you can buy separately, of course. In summary, this is a great product with a lousy container. I'm recommending this product with the noted reservations.
