## Customer Reviews

### ⭐⭐⭐⭐⭐ Peace of Mind!
*by J***G on April 18, 2025*

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.

### ⭐⭐⭐⭐⭐ Works great

### ⭐⭐⭐⭐⭐ A must have item to have in your tool box or shop.
