I'm surprised PB gave it a thumbs up after all the negatives he had. Personally, I like the 510 connector although in reality all it does is move the gap to between the 510 ring and mod body.
I ended up having to re-coil and re-wick today. I was playing with Kanthal tanks and my Ni200 build, switching back and forth between them, to see if mine had any "identity" crisis problems. It didn't which seems strange 'cause according to PB's video mine should be a version one based on the packaging. It has forgotten settings a few time, but each time there has been either heavy vibration or a sharp shock involved which leads me further to thinking it's a bad battery connection or a bad connection internally.
My original build was a nominal .13 ohms with 10 wraps of 28 gauge on a 12 gauge needle, wicked with rayon. I tried it at 50 watts, keep in mind this is on an ErlK clone, and burned the heck out of it. It did clear, but I didn't like the flavor at all so I rebuilt it with 10 wraps of 30 gauge Ni200, tempered, around my trusty 12 gauge needle. It came in at about .18 ohms and is wicked with rayon. It's a really nice vape and I really like the Invader.
