You may take a look at the Vandy Vape Simple Ex. Its a super small squonker.
4ML juice, 4 different power settings (constant) and rebuildable.
OR a small 2ML tank with an 18350/18500 tube.
I've been using the Simple Ex as a daily device for quite a while now. Bought two of them when released. The first one, the plastic squonk door developed a crack and ended up completely splitting in half. I'm using the second one now. If it suffers the same fate, I will simply switch over to using a OG Pico Squeeze with an Ammit RDA. When I build it around 1.5 ohms (28g kanthal) and use an LG HG2, I can get a few days in between charges. It's hard to beat that. And doing MTL with nic salts, I can get more than a day from a bottle of juice as well in the Pico.
You know though, even if you don't squonk, it's a great option for a small MTL vape device (Simple Ex or Pico). Don't have to squonk often at all. Simple kanthal builds work great.
I was using the Minifit when on vacation a few months back, had been vaping DTL for a few years. After getting back, I built the Simple Ex, and have honestly been using it more than my other gear.
I like the Minifit for travel still, but when I'm not travelling, the Simple Ex or OG Pico Squeeze is small enough for me. I really like my full size gear, but I'm having a hard time going back to DTL, lol. Really liking MTL at the moment.
My last box of pods in the Minifit, I've been unable to pull the plastic chimney from the base to rebuild them. So far, two out of the three pods in that box seem to be glued on. I've got several more boxes of pods, but if they started gluing on the chimney, I think I'm done with the Minifit once the pods I've been rebuilding are shot. I brought this up in the Minifit thread, hoping others will keep an eye out for this and confirm or deny as they use current pods they've bought.
