Innokin mods Refresh feature

[digicig]

Aloha All
Having been in China for the last few years - and in the last year, Ecig tat being nigh on impossible to get except pods and then disposables - finally back and able to get a choice of mods etc

Going for reliability based on past experience - and Innokin certainly have provided that for me.

So bought a Z80 for 18650 option and now received a Kroma 217 via Health Cabin - and both have the Refresh option in their menu system.
The idea is that by using this feature it prolongs coil life and boosts the coil when the flavour becomes a little muted or less vapour production drops off. It seems to 'send' a burst of 40% power through the coil to 'shake' it and 'rejuvenate' it. Refresh can be Auto for a quick Refesh - or Extended set by the length of time you hold the Fire button - for longer used coils.
Whilst this seems likely to be aimed at Innokin stock coils - I've mainly been using this feature with my Rebuildbles - those moments when I'd usually be thinking of rewicking the coil (especially late at night when to do so is unappealing) for example.
And it seems to do enough for me to wait until a more convenient moment.
Any other thoughts, experience or advice?

The Kroma 217 also offers a Coil+ feature - supposed to increase/enhance coil life - either for Watts or Volts mode - which apparently does the same as the Refesh function - but every time you press the fire button.
Using this feature, however, means that the Power option offering 3 levels of intensity: Soft (my preference for a long slow MTL vape), Normal and Hard (better for DL or Stealth vaping) is disabled - the display showing either C+ or S,N,H to remind you.
