I had to do the 5 click thing twice to turn it on. My ZNA 50 is def heavier and feels more substantial. Whatever pwm or rms the IPV Mini is doing, the ZNA 50 seems to do it better for both my nautilus mini tank with Cosmic Fog Nutz, and my Infinite Hobo clone with same juice (50/50 6mg).
Finally turned on the IPV Mini, and tried the usual combinations for changing mode etc. yes, I know, reading instructions yada. I was trying to figure out how intuitive it is in the intrerest of recommending it to new Vapers. It started firing the atty and wouldn't stop until I turned it off. Not good.
Turned it on and scrolled through the memory until I reached the closest to my usual vape on the hobo (28 AWG 9 wraps dual parallel .9 ohms) which is 16.5 watts, and it tasted not burnt but more like over cooked.
I'm still playing with it to find a good vape on it, but the fact that it's taking this long is not a good sign.
ETA: Also, the Hobo WILL NOT sit flush on the Mini. It's also reading the Nautilus BVC 1.5 ohm coils at 1.9.
Hoping you have just rushed to judgment or maybe are not comfortable switching to a Mod with different functions quite yet. I would recommend spending a little time getting used to it.
I also recommend All people read Directions thoroughly on any Regulated Mod before using. We can all learn form those that build the devices.
As to Miss-reading Ohms - I would be concerned. I would also recommend further testing, perhaps against a known good multimeter.
If there is a continued variance, contact your Vender as the unit is likely defective.(it happens)
**Auto Firing** - Fiddling first possible lead to putting into Power Bank Mode - Continuous output to charge another device.(in the instructions

)
For performance comparisons make sure you are in DC-DC mode it is incredibly smooth and powerful.
5 Clicks not registering is not uncommon. Many Many mods do this and simple need to be woken up first to take a command.(respond)
Almost all respond to a single click with a very short delay and then 5 clicks. Give it a try on the next cold start up.
I ordered and am testing 2 of the Black IPV Minis.
So far the biggest problem I have had is getting them out of my hand.
Performance is outstanding and they handle anything to .5ohm flawlessly so far.
Ohms readings have been spot on to my ohm reader and commercial quality multimeter.
Even the low power warning works perfect. Could not get one to fire this morning, but finally looked at the screen.

Swapped batteries and back in business.
Would I recommend this for a New vaper - NO
Not this or any other higher end device. NEW Vapers do not need to jump into the Deep end of the pool. Let them work their way in with confidence. There is plenty of decent gear available that is simpler and will provide solid support.
