I actually had some success with that last night - shortened the hose which is attached to a bubbler too but still cant really go past minimum settings.
I'm using a 220V unit. Lowest power draw is 22-23 W and the max is around 32W so it's not just off/on the heating is variable. Element glows at both min and max setting. I took some photos to show glow but haven't worked out how to post them.
Edit... Or have I?
30 seconds after switching off
Maximum Setting.
Minimum Setting.
Yeah, as
@hoptimum said, that is definitely running too hot!
I'd contact 7th Floor like he said and see what they say.
Sorry for your troubles, bro. It worked perfectly the day before I listed it.
I used it all day at 12pm-1pm to make sure all was well and as a 'see ya later to the buddha' session.
Was it that hot during your initial session?
Hopefully 7th floor says it's something easily fixable.
edit: just dug up in my email that I bought this unit on Jan 24th, 2013 from theothersidevapes.com. They list the DBV as having a 3yr warranty. If you need me to send
you the email invoices as proof of date of purchase for 7th floor, let me know.
