Seems like going back to the initial Goblin launch there were direct comparisons made to the Silverplay. Well now vapordna / PROJECT SUB-OHM® has their answer to the Goblin Mini getting ready to launch, the Silverplay Nano.
Project Sub-Ohm SilverPlay Nano RTA Rebuildable Tank Atomizer
Looks nice, costs a bit more than the GM, but does give you a bell cap included. The SP Nano is 33mm tall vs 28mm tall on the GM, but SP Nano vs GM w/ 510 DT adapter would probably seem rather negligible in height. Bottom fill looks like it will be easier to use the glass bottle dropper style bottles if that was an issue for you on the GM mini. Doesn't look like there is AFC, so this is most like a lung hitter only type rta.
