Already got rid of my IPV5. If it's anything like the Reuleaux I didn't feel like chewing up battery wrappers.My second was delivered today and I threw an NI coil on it right away.
It metered at .15 and when I put it on the device and set it up it came in at .15 ohms. Let's hope that streak continues.
I have it set up at 33 watts and 405° and the vape is very nice and consistent. I've vaped through 3/4's of a tank and the device has been solid.
jstrong, those battery rings are supposed to be a safety feature much like the reuleaux to keep the batteries solidly in place.
