Call it strange, my SB is probably my favorite mod (and yes, I have a GGTS and Provari along with some other higher end mods).
It is a champ and quite frankly, as said on the Vapecast podcast, a mod that will survive for a long time thru the ecig industry.
Yes, it isnt perfect but no ecig is (I challenge anyone to find one!!)
But it is the mod that will handle being run over by an 18 wheeler (18,000 lbs in the tractor alone) and doubles as a weapon (tho not recommended).
What I really like the SB for is unique design in the 510 connector. I have placed a brand new 510 atty on it, used some pliers and pulled the metallic tubing away from the atty heating element and the SB survived just fine. Very few ecigs can handle this kind of stress on the connector. The SB is my go to mod when I need something that will just keep ticking.
And the button design is to die for. I really like the button. I find myself pushing the button just because it feels good. It feels right. Call it bizarre, I am really fascinated by it. It fills my OCD disorder. It is smoooooth. The button is probably my favorite thing about the SB.
I havent found a single 510 connector that wont fit BUT, if you are concerned about this, you can order either a 510 extender which is basically a threaded tube that extends the length of the connector above the top of the mod you are using it on or you can order a 510 to 901 adapter and a 901 to 510 adapter, screw these together and then screw them on the mod. Either of these solutions will give you a longer connection if you need one (and potentially will save the threading on your mod).
