Pros:Improved resistance to shear shocks relative to ordinary super glues.
Cons:Can set in the bottle, will set in the tube.
The Bottom Line: Gorilla Super Glue isn't just brand-name cyanoacrylate; suspended latex microparticles make it more resistant to shearing shocks than ordinary super glue
Cyanoacrylate "super glues" have been around for over six decades, and the common varieties--runny liquid, gel, quick-setting, etc.--have been around at least since when I was a small child who liked taking things apart and putting them together. It's thus safe to say that innovation in super glue is rare. The makers of Gorilla Glue, however, have truly improved on the usual with their Gorilla Super Glue.

Most super glues set to solid polycyanoacrylate; Gorilla Super Glue is a colloid. Latex microparticles are suspended in the cyanoacrylate solution, supposedly to give better resistance against shocks and shearing. I have yet to see comparative scientific tests of resistance to shocks, but testimonials to this effect are becoming common on the Internet, and are compatible with my experience.
Gorilla Super Glue is holding together the impeller of my Whisper power filter, in a joint subject to both tensile and shearing vibrational shocks when restarting. When this was being held by conventional super glue, the joint held for perhaps one restarting cycle before having to be re-glued; the Gorilla Super Glued joint is considerably tougher. Strength against shearing isn't comparable to that two-part epoxy, but it comes without the waste or the wait.
Strangely, Gorilla Super Glue is transparent. One would thing that better shearing strength could be achieved were there enough microparticles in the suspension for noticeable turbidity, perhaps at the expense of some of super glue's renowned tensile strength. Some people prefer their super glues to be clear, but for most applications, it doesn't matter to me.
Application is the same as for any other super glue; apply a bit to both surfaces, being sure that they are smooth, as cyanoacrylate glues are poor gap fillers. Clamp for thirty seconds, let set further for several minutes, or overnight for maximum strength, and put the repaired part back into use. Two different package options are offered: two metal tubes with plastic tips, or a single plastic squeeze bottle with a metal pin in the cap. The former clog within days of opening; opt for the squeeze bottle. Cleanup is with acetone, and the usual tricks, such as instant bonding of cuts or gap filing with baking soda, all work just as well as with conventional super glue.
Gorilla Super Glue isn't going to replace two-part epoxies in my utility cabinet, but it's certainly enough of an improvement on ordinary super glue to make it a convenient substitute.
