Did the same thing a couple of months ago myself. Felt guilty tho because I was getting great service from my Joye's.
Only upgraded because I really started to only enjoy the first few hours on an unregulated battery. Apparently I'm a 3.8,9volt, 7-7.5watt vaper.
Could have got this same experience on the Joye unregulated Upgrade's if Boge had a true, 2ohm or less, carto.
