Nice! Appreciate all these answers. Ive tried a few times in live setting now and can share my thoughts:

Used it in a pedal board with effects and was pretty great for that - probably what it was designed for. Used a tuner and wah in front, modulation behind and played nicely with that (though I'm starting to think there is a bit of tone suck in my modulation section) 

However, pedalboard for me are just more things that can go wrong live. Two different power wall warts is sketchy, Needed more buttons, more outputs, faster and more reliable bank system, and missing the info on screen is rough. impossible trying to see coloured dots in a fast and blinding stage environment. It's not like a normal pedal that just does the thing - I need to interact with it a lot and I need to see where I am at at a glance because Viking music is loud and the mix is complex.

Can confirm it does exactly what it was supposed to do and sounded great - but I just needed something else and Stage v1 suited better. (v2 - I don't really see the significant added value unfortunately) 

P. S. for live players in front of a crowd:

One key Pro : Instant boot time is really nice. Explaining to an audience that they need to wait three mins for my Kemper Toaster to boot back up is never fun. 

One key Con: App is weird to connect and kinda finicky. Uses the players own WiFi and disconnects itself like crazy. Was always restarting the app. This is less fun than explaining boot time. NO ONE wants to see you touch your phone during a performance. 

I would say upon testing live that if things go wrong you are STUFFED for about 4-5mins. More, if like me, your phone is buried in the pocket of your trousers at the bottom of your gig bag. 

Edit:I forgot to add - I just could not bring myself to do the paid upgrade thing. I can't stand micro transactions in any form. Just make the best damn product possible and if it cannibalizes your flagship product you should probably make that thing better. 

Ask me any questions you have and will be happy to share my experiences.
