### ⭐⭐⭐⭐⭐ Works
*by K***N on January 11, 2026*

Works well and very strong hold

### ⭐⭐⭐⭐ Different fill levels.
*by D***Y on October 15, 2025*

Loctite Primeless Thread locker 263 250mL Red we ordered two and one didn't seem as full as the other. Other than that there were no issues.

### ⭐ NOT as advertised!
*by B***E on May 20, 2023*

Don't order. It says your getting 250mL but the bottle is less then half full and there was no seal on the bottle. Waste of money.
