    Lol! That joke at the end made me laugh.
    I wanted to ask an honest opinion. I believe you guys are sponsored by rectorseal. So, I’ve known about the Migrare Sspin swage and flare bits for some time now. And just last Friday I put an order of both the sets. I still haven’t gotten then yet. So as I was looking at demonstration videos on YouTube I came across the rectorseal brand ones. After I have already order the sspin ones. Till that point I wasn’t aware they also made some too. So which ones do you guys at HVAC school think are better? Honestly.
