I've had a Pinnacle Pro for about 4 months, so I'll chime in to say its a pretty good unit.
Hands down wins on stealth in public. Most people just think its a fat e-cig and I never get a second look. The bullet system is also pretty good for those on the go, just dump the old one (although you don't really want to hold one straight out of the chamber...), load the pre-packed new one and you are away in less than 5 seconds. Although buying the extra bullets does add to an already pricey unit - I don't think I'd like this thing half as much without them (also get the bullet holder, but be prepared to put some foam in the lid to make the lid fit properly).
On the downside, the battery life is average. If you're planning a heavy session, you better have an outlet handy. I generally get 3 - 4 decent sessions out of it, which is a pain in the a$$ if I'm out and about all day. Really needs a swappable or better battery, or even a Car charger. As Bleak has already said, it's the trade off you get for the size.
There's also a few reports over at fuck combustion that some people are getting problems with melting mouthpieces. I've never seen it, and I get the PNP up to the highest setting all the time. Either it's a vocal minority, or I've been lucky for the 4 months I've had it. They've also just changed the mouthpiece design so it has a glass insert. They are replacing mine for free even though it's not broken, so I can't complain. If you are looking at getting one, make sure it has the new glass mouthpiece design and not the old one.
Most importantly this thing hits decently. If you've got the time, it'll make your weed last and last, but if you are in a hurry just crank up the heat and get it into you (not as efficient though). Taste also gets a bit funky at the upper temps - is great at low/mid. It's supposed to do hash and concentrates as well, by using a special bullet. I've never done it, but the guys at FC reckon it's not the greatest at this. Best to do it as a weed-hash-weed sandwich (or in cotton for oils), which generally gets the thumbs up from those concerned. There's also very little learning curve, which comes in handy when sharing with mates. And finally, do yourself a favour and get the water tool with it as well. Best travel bong combo I've ever owned.
And for those who don't know if you'll like the stone (it's definitely different - not as heavy maybe?), see if you can borrow one for a couple of weeks and use it exclusively. I was a bong user for 20 years and can't see myself going back to combusting as I don't feel like I'm missing out on anything.
Well that certainly went on longer than expected.
TLDR: Great vape, crap battery. Get the water tool, extra bullets, bullet holder and new glass mouthpiece design.
