It's kind of a shame, as some of the coils included would be great if they used SS, or at least identify what the coil is actually made of. They leave it a guessing game. Funny thing is SS is really not expensive so providing coils that can be used in both power and TC would be a nice treat for their customers.
Just so. I preach safety to coil builders like it was a religion and I a prophet. Know what you're building, I tell them. Figure it out in Steam Engine before you touch a piece of wire. Measure those coils, boy! Don't over load your batteries, whatever you do. And on and on and on...
So, now I'm gonna tell 'em, hey, no problem! Some Chinese dude got paid 23 cents an hour to wind that coil, and since it came from the manufacturer it'll be perfectly safe no matter what? Please...
Oh well, at least we're no longer getting a 5 spaced wrap 40ga coil around two pieces of silica.
