Strong and stiff

### ⭐⭐⭐⭐⭐ So nice to have
*by J***E on February 24, 2025*

Makes life so much better

### ⭐⭐⭐⭐ Mixes nicely
*by C***I on December 2, 2024*

I use these in shore 10A - 020 silicone, and they power through without adding too much air. There are tiny gaps in the welding where the mixing blades are attached to the rod, and material can easily get stuck there which is hard to clean out.
