## Customer Reviews

### ⭐⭐ 







  
  
    Check the smell of the smoke before you apply to components
  

*by C***T on Reviewed in the United States 🇺🇸 on October 14, 2015*

Yes this is a very good price, but I'm marking this as 2-Star only because container has NO MARKING in English indicating whether this is really supposed to be rosin flux. Content looks VERY different from other rosin flux from other suppliers. The proof will be in when it smokes off hot soldering iron... which I have not had time to do yet.

### ⭐⭐⭐⭐⭐ 







  
  
    good stuff, not contaminated in any way
  

*by J***. on Reviewed in the United States 🇺🇸 on February 3, 2021*

melt action and flow is awesome even @ 385 degrees.

### ⭐⭐⭐⭐⭐ 







  
  
    Improves solder joints.
  

*by D***L on Reviewed in the United States 🇺🇸 on April 2, 2015*

This product makes soldering heat sensitive connections much easier, and it improves solder flow and reduces "cold" solder joints, it also reduces the heat needed to achieve a good joint.
