Peace of Mind!
Great Product and value! Have always used name-brand thread locker such as Loctite. Has never failed me or let me down. I have never used the off-brand thread lockers, so I have no opinion on those. But I know from personal use this red Loctite works like a dream. This is the perfect size for small projects, a the size is easy to apply. I use the small tube for RC car and truck projects.

Very nice quality
Careful were you leave the tube when you are done, it leaks on whatever you place it on. Put it in a zip lock bag.

Easyest Thread Locker to use.
It's not as permanent as they say, but good enough. I particularly like that you can use it without a primer on slightly oily fasters.
