got an evic vape mailed, and I wonder, is anyone else having "glitch" issues. sometimes the batt just drains, power off, sleep, doesn't seem to matter. sometimes it won't turn on even connected to pc through the usb. also, the actual voltage seems to be lower from what the screen is saying, compared to comparable setting on other variable volts spinner or twist. sometimes it vapes great, turn it off, come back to the same setup, use the same settings, and it's weak. "recommends" the same wattage regardless of resistance of coil ohm? and the twist knob/dial sticking? Sorry, probably been asked and answered, but this "manual" isn't exactly extensive or informative. sound like a bad unit, or is this typical? as always, thanks in advance.
