If you get a Health that works, it's a good cheap beginners model. But there's a high failure rate with those devices. They're cheap, after all. You should move up from that to a better model as soon as you can. I would reccomend the Janty KISSBOX Yentyl,if you prefer the mini style; it's a much, MUCH more expensive model of mini, but it's performance is well worth it. It's a much easier draw and produces more smoke than the Health, it has longer lasting cartridges and batteries, and it comes with a choice of manual or automatic switches.
http://www.ruyanxpress.com It's around $125 US, but it's easily worth the price.
Or if that's too steep, there are other options. Do a search on super-minis on this site, someone just posted a cheap e-bay listing for 2 good super-mini e-cigs for about $50 with shipping. It's a superior model to the Health, and at two for the price, its a bargain. Or get either of the minis from
http://www.e-cig-sales.com ; they're the previous generation of Janty Yentyl, and they're $40-$60 price range. Best overall performing mini short of the Kissbox, IMO.
