I'm actually enjoying the Kanger Aero Tank the most with my VTR. No need to chop up the VTR and the ring gives me added security for the glass like it was meant to do. At a measly 3.5 volts and 7.5 watts I'm blowing huge clouds of DIY 50/50 Vanilla Cupcake. It's a great MOD to use!
I have an Aspire Mini mounted into mine, the new Aspire BVC atty is a huge improvement over the performance of the old BDC atty.
The Mini will fit into the VTR just fine however you have to disassemble the mini's base and pre-mount it into the VTR and then fill/re-assemble (upside down of course). Yes I have seen where folks have cut away the protective ring which does make it easier to mount other tanks but then that defeats the whole purpose for having it.
I've been using the new Beyond Silo Lite and the Aspire version of the Vivi Nova Tanks
The kanger Aerotank V2 and EMOW
my backups are just about any kanger Evod 2,, T3 or Aspire ET-S BVC Pyrex glassomizer with the ego/510 adapter on the bottom
This way I only have to buy 2 type of coils for everything.
