My experience with the mini ST I got 2 weeks back:
First rushed trials of the 2 OCCs that came with it was a huge disappointment, I figured they were not meant for mouth to lung, regardless of power settings. Hot vape and throat terror, nothing pleasurable and not hint of flavour.
I tried very fast to save the high expectation by dumping the coil in the RBA, which looked very much the same as those in the OCCs, and rebuilt it to my custom coil> 28 gauge 2.4mm drill 8-9 tight wraps, threaded it with cotton and... WoW!!! high expectations exceeded! but... with the blast of extended flavour was a hint of machine oil.
Empty the beast to wash/ cleans it.
2nd disappointment: not easy to clean, inaccessible inner air tank section and too many complicated components /seals to clean. 1st clean, reassembly> machine oil hint still there. Completely disassembled the RBA to rub it with alcohol, and that did it.
With my expectation exceeded, I had some patience to rebuild the OCCs. Not my definition of easy to do in a few minutes, and the various outcomes of a few struggles were not pleasurable at all. I quit trying, the RBA flavour was already more than I could ask for.
This clearo makes one feel enabled to taste each individual components of the ejuice vaped. I should try
vaping red wine
The 2nd disappointment for what initially appeared to be a not easy to wash/ cleans clearo later also vanished, further to a few refills/ re-wick. I noticed the
juice compartment never gunked, the juice always staying its fresh initial colour, so that bit never needs to be taken apart and washed with every re-wick, as I previously had to do with the Kayfun type clearos. The only maintenance required with each re-wick is a wash of the RBA section, and dub drying the inner air tank with ear buds. Loads faster to do than with Kayfuns.
I figured that the juice compartment staying clean had to do with the larger air intake not causing an under pressure pulling too much of the juice at each draw, and letting part of that + gunk being sucked back in the tank after the draw.
Also, this tank can be filled to the max, you don't need to keep an amount of air on top of the juice to avoid the burning taste, as was recommended for Kayfuns.
Impressed!!!
