I'm inclined to think the ones profosist and I got were "counterfeits"
They may be "generics" and they may work "just as well", don't know, haven't used mine, but they should not be selling them under edsyn soldapullt, because that's not what they are.
and you can see there's a DISTINCT missing Notch on the EDSYN soldapullt on the handle in the back,, while the generic one I purchased does not have said notch...
