i have a weird issue. Have about 4 smileomizers that i switch out throughout the day, and i haven't had an issue like this in the past with the smileomizers and the DAV, but now if the DAV is turned up to 4.8 volts all of the smileomizers taste like they are burning. i have to have it turned down to 3.2 in order to get a decent flavor from the smileomizers. Is this something that's an easy fix? I'm just afraid the DAV might be using more volts than the dial is saying and it is burning out the smileomizers. I used them with a Titan battery yesterday, and they tasted fine.
