Excellent blue/removable thread locker!
Fantastic product that holds tight but is removed with reasonable torque. Bottle and needle is done well and doesn't leak or make a mess. Dries quick and sets to full strength in 24 hours, color is just like the brand new stuff that's far more expensive. The thickness/viscosity of the fluid is the same as the name brand product. Overall this is a quality product at a great value and performs exactly like the name brand product. You get a half a life time supply for very little money.

Great hold. Easy to use. Not expensive at all
It works really well. It’s held for 4 months so far and still holding. I’ve used it on multiple occasions and not had any issues yet. Great value for the cost.

Just lIke the brand name stuff only half the cost!
worked great for my needs. No leakage from bottle, should last me a long time as there's plenty of it! Applies smoothly with no mess and the perfect size. I used it on the threads when replacing a PCV valve in my Subaru Outback.
