Yep. On all the time, except when we're away on vacation. When we get home, the first thing I do, though, is plug it back in.
BTW, while on vacation I picked up a glass mouthpiece I'll be trying out with the PD later on. It is just a clear glass tube with one narrow end and one GONG end, shaped like a sherlock. They are sold as ashcatcher attachements, so you can use your ashcatcher without the bong. I'm just going to stick my PD tube in the GONG end. I think it's gong to give a little more cooling and maybe a bit more laid-back inhale posture. This will also be used with the Vaporstar. The Vaporstar is primarily for those times when I find the PD cold.
Ususally due to someone turning of the wall switch. I gotta lock down that wall switch.
Update:
Now I've tried it. I vaped one stem and thoroughly enjoyed it. The vapor is significantly cooler than when vaping naked the posture is very natural. I held the sherlock in my right hand annd held the PD with my left. With a light on next to me I could see the vaor clouding up the stem. Not thick, though like a bong. After lifting off the PD from the stem You can then separate the stem fro the GONG joint by just pushing up with my thumb and index finger. I feel the hits are bigger than naked but not as big as you get by vaping it through a bong (mine is a 10" Delta9 beaker).
The wife just tried it. Her report:
I like it. Tastes great. Second hit:
Its so nice, it dooesn't make me cough!
