I ended up buying the Cobolt black Spade after seeing it in person; solid, awesome quality device
- Bottle system is great, effortless to remove/refill with zero mess.
- Battery is a cinch to put in and take out with no worries about damaging the wrapper, very easy to shore up battery rattle.
- Button press is definitely on the firmer side out of the box, noticeably stiffer than the majority of mechanical squonkers but can be adjusted.
- Door panel tolerance is fairly tight, was thinking of sanding the edge a little but will wait a while and see if it wears in on its own.
- Full disassembly was a little tedious, but don't see any reason to do it regularly.
- 16mm 510 base is perfect since I only use smaller atomizers. 510 pin is spring loaded, not too stiff, tension is just right.
- Comfortable grip with the curved/flared sides.
