Easy to use, works great.
Used this to fix a screw on my elliptical machine that kept coming loose when I used it. Very easy to use, just squirted the Threadlocker onto the bolt, attached it to the screw, and let it dry. It never comes loose anymore.

Good Value
Much better value than actual LOCTITE brand name. Does the same thing at a fraction of the cost of a bottle of LOCTITE brand.

Screw cap snapped off.
After 2 to 3 uses, threaded nozzle broken off the main body. Unable to replace the cap wasting balanced amount.
