got my proteus last week and tried several setups.
i´ll tried with a titanium wire i had already for a while.
i was dissapointed, because vir doesn´t works well.
burned taste and battery life for just about 10-15 minutes.
so i decided to buy real titanium wire grade 1.
today i made my first wick, 6 wraps around 2.5mm screwdriver of 0.3mm wire.
and now i got all advantages of proteus.
the taste of my penny v4 is unbelievable.
just opened the liquidcontrol one turn.
no problems with burned taste at 230°C, full taste and a lot of flavour.
vaped till the tank was empty and proteus quit firing as expected, battery life for around one hour with my aw batteries.
now i am expecting a new button housing for esterigon
