I used it once and had the second best high in my experience, right after my first time. It's easy on the lungs, saves time, it's economical (you really don't use much bud), and doesn't give off too much smell if that's something you want less of, but they are pretty expensive. But then again I don't really smoke much. My friend absolutely loves his though, and he's a big smoker.
I don't like it. I don't think it gets me baked at all. I could be doing it all wrong but I've tried a for a while now and yeah I feel it, but it's not as good as a bong hit IMO at all, maybe I need to try again. Batteries are pretty useless I wouldn't mind trying a power adapter if they have one made yet. I actually have some ground up leftovers almost like a powder, maybe I'll give that a go. But from my experience it doesn't get me stoned, just a background buzz.
And it's been sent. Now I tried it again last night, two trenches approximately made up 1 cone piece that I'd normally bing on with. I take two cone pieces per session. 1 trench gave me similar buzz to what bing session would have done. So it definitely saves your green on that respect. My tolerance is through the roof but I believe after a decent break the vape could work wonders.
I've had it for two years and use it all the time still. I have become a real fan of vaping. If you have a high tolerance you probably won't enjoy it quite as much but if you have a low tolerance it provides a great high. It's a great contraption. Very convenient and stealthy. My best purchase ever. Definitely check eBay for better prices.
I recently got one, and after useing it for two weeks I can't go back to smoking pipes or bowls... the taste alone makes me want to continue using this forever! I Got so high, like more so than I have in YEARS, probably since I started smoking. It's super convenient and much better, I am glad I got it. You can get better prices on ebay sure but the lifetime warranty is worth paying the right price for it. It covers basically everything so you know if something ever fucks up you will get another. The batteries are the only problem with it I hate charging them over and over, so the power adapter will be a purchase soon so I can use it more constantly at home! Save the batteries for travelling! But yes, worth the money big time if you want to get the cleanest and healthiest high you've had in ages!
