Willard & Tim,
Thank you so much for replying back, much appreciated! I use the 3.5ml tanks w/ 2ohm dual coil carto's & keep my DAV @ 3.8V-4.3V. But like I said, on my 1st DAV I remember I had issues getting it turned on. They are both manual. I just read Tim's last post, clicked the new DAV 5x QUICKLY & low & behold, it fired up! So for others new to the DAV, it's a quick 5 clicks to turn it on. ; ) Thanks again!
