Hey seelos. I've got both the herbalAire and the Purple-Days. My herbalAire is two years old and I've used it almost daily (my wife likes bag delivery) until this past spring. I bought an SSV and started using that almost exclusively, while still doing an occasional bag with the wife. Then I bought the Purple-Days vape in early May (looked like a great deal and a big improvement over my Vapolution for home/portable use) and settled on the SSV and PD as my only vapor systems. The PD is so efficient and easy to use that my SSV use went from almost 100% to about 35-40%. I love the high volume vapor hits the Surfer can provide, so it will continue to be used on a regular basis, just not as much as before.

What really ended my herbalAire use altogether was my wife falling in love with the PD. It's the only direct draw vape she's been willing to use. In fact, I'd be using the Surfer even less, except that she tends to hog the PD.

Aside from build quality and simplicity that should allow the PD to last long enough to become an heirloom, it offers vaping pleasure (hell, I love just holding this little jewel) and taste you just can't get from the herbalAire. No, it doesn't hit BIG like a full size whip vape, but it is surprising how much vapor you can get out of a bowl that only holds about .02g. The herbalAire, with its 18 tiny outlet holes in the bowl area, doesn't allow for very satisfying direct draw hits (it is effective though), and bagged vapor, whether it's the herbalAire or the Volcano, is always going to be diluted with the pumped in air, and therefore not as rich in its hits.

While I hate to advise you to sell your herbalAire in order to buy the PD, mine is sitting idle and collecting dust while the Purple days vape gets daily use. It's also great as a portable, with only the long warm up time as a minus. OTOH, the big stainless steel heat exchanger that requires that 30 warmup, also is responsible for excellent heat retention, allowing for hard and repeated hits without dropping the temp down below vaping range. Just yesterday I used my Vapolution battery pack to power my PD. It let me enjoy a couple of bowls while sitting in a parking lot, waiting on my wife to get a hair cut. The big heat exchanger will also allow you to disconnect the power cord and take the PD to another room and vape a bowl off the stored heat in the exchanger. I'm pretty sure no other vape on the market can do that. The temp would drop too quickly.

I can't say you won't miss the herbalAire if you have to sell it, but I can assure you that you won't suffer from buyer's regret if you get the PD. It's an outstanding vape and probably the best bargain out there, considering the build time involved for a $150 price.

Vapenow.com has just started selling the PD, but I suspect he won't be the 'exclusive dealer' for long. I would recommend the purpledays site though, for a personalized buying experience.
