Don't forget about Replay. I know DNA 75C or 250C mods ain't cheap - but it's worth it. With replay you just fiddle with the power (watts) until you get to the vape you like then hit 'Save puff'. No TCR worries - no fiddling with Escribe. It just repeats that 'vape' that you saved. It's basically TC plus. Why TC or Replay if your a MTL vaper? Before 'TC' I found that the first puff would be too cool, second about right then the third too bloody hot. So I tried TC. Started with the Pico - its TC control is OK but nothing like YiHi or a DNA mod. So I suppose its down to vaping style - short puffs - why bother with TC. Long puffs - can get hotter & hotter. Mix it up - then TC comes into its own.
