I purchased this for some prototyping and testing purposes and, for the most part, haven't been disappointed. For a few bucks there was enough in the tube to work out some basic issues with my design idea and still enough left to make a final "proof of concept" to take further through the design process.Something I wish I would have known from the beginning though is how weak this product adheres to smooth surfaces. It scrapes off like cake frosting after drying on smooth plastic, glass, and metal. I had to artificially add a rough surface to a 3d printed part to make the product stick well enough to use more than once. It's neat, but that limits it's usefulness quite a bit.
