Review on Soldering Station Solder Replacement FX 951 by Aaron Collins

I want to start by saying I haven't tried them all in the pack yet. The ones I've tried work great with my ShineNow T12 soldering station. I've used leaded and lead-free solder with no problems. They heat up quickly and hold it. They seem to work at or near the same temperatures as the tips that came with my kit. I didn't notice any noticeable difference when soldering.
