I recently tested out a 4-pack of cyanoacrylate adhesive in the Adhesives & Sealants category for my industrial and scientific work and was very pleased with the results. As a result of my tests, I determined that this adhesive bonded solidly and quickly without leaving any residue. It was also very easy to apply and the small tube size of each individual pack made it easy to carry around. However, the only con was that the glue had a strong odor that lingered for a while. Overall, I would highly recommend this adhesive for any industrial or scientific purposes.
