So been using my iStick TC100 for a few days now. I am enjoying it as a backup to my
dna-200 (which needs to be charged midday). The battery life is nice and I can go at least a day (chain
vaping).
One con I have noticed is it gives a low battery warning starting at about 25% and wont fire unless I press the button twice. It only does this if it has been idle for a few minutes. I would prefer it not interrupt my
vaping habit by giving me a low battery warning. But with upgradeable firmware, this might be something they could change in the future. Again, not a huge deal, but it is annoying at times.
The TC seems to be fairly accurate (that's going to depend on your wire and TCR setting). I think it is probably more accurate using the TCR, but seems to work well enough using the preset modes too.
Overall, still happy with it.
