Hi Hammy. Yeah I'm about 45 minutes from Mojo Vapes and I picked up 2 Isticks this afternoon.
Note to all here: I'm insanely fussy (OCD) about details with QC, even cheap stuff, which is why I prefer to buy from a local B&M if possible so I can analyze and test everything. I picked up a silver and black. The black was fine but the 1st silver had a slightly crooked display. The 2nd had a good display but had a couple noticeable flaws in the case casting. The 3rd was just right. Gee I feel like Goldilocks
Shortly after I left I noticed the non-firing button issue. Having read this thread I immediately kept pressure on the button and pressed even harder but still no fire and no display. I then released the button and it clicked as normal when releasing any other time. I felt quite sure my finger was in the middle of the button. So I guess its still a bit of a mystery and hasn't happened again since.
Initially both Isticks appeared fully charged and as others have mentioned, I also noticed that I had to set the voltage lower than I do on any of my other devices to get the same strength of hit.
I then checked my black one which still appears fully charged and just now I tried a Kanger Aerotank Mini on it with the 1.5 ohm dual coil which for me can never be pushed past 3.7 - 4 volts max without tasting burnt. I set the Istick at 3 volts and sure enough it hit hard and the juice was popping like it was about to explode but oddly it didn't taste burnt.
I then put a fresh battery in my Sigelei Legend V2 and set it to 3 volts and the hit on that same tank/coil was quite weak.
So regardless of how the Istick is readng its voltage, I can clearly see why many users are saying it hits too hard on some of their setups compared to all their other devices.
As others have mentioned, I will just ignore the settings and simply adjust it to taste, and since I mostly use consumer coils in several Nautilus Minis and an Emow Mega tank, all of which start out at 1.8 ohm and quickly go to 2 ohm after a bit of use, its so far hitting perfectly for me every time. I'll just reserve the Aerotank/1.5 ohm tank for my matching Evod VV batts which adjusts voltage perfectly for that tank.
