Haus is a "value" brand personal vaporizer made by mistic. Mistic has been in the e-cig business for a long time (well, as long as a company can be in a field that just started in 2007). This is the PV that got me started in the world of vaping. Even if it only lasted me a week or so before I had graduated to bigger and better things. At least it showed me this was going to be something I liked, better than my analogs (normal cigarettes).
They sell these things at Wal-Mart and several other places everyone has access too, so that's nice. The price isn't great, but it's not terrible. At Wal-Mart the starter kit is currently $19.99 and juice is $6.99 or so. So you can get a working setup for around $30, or a little less. That's about right for lower end, starter setups.
The battery is a 650 mah standard E-go type pen setup. They are using a custom battery in this thing, because it's shorter and fatter than a "normal" E-go pen of the same class. But otherwise it's your standard E-go. And as far as that goes, it's a great looking and working E-go pen.
The downfall on these is the tank. It's some kind of SBC (single bottom coil) CE5 type knockoff. I bought two of these kits, one for me and later one for my girlfriend. And we both stopped smoking on these, however the tanks flood after awhile. The atomizers are not replaceable, so you have to buy a whole new tank for about $7. This annoyed me, that I couldn't keep them from flooding, and it annoyed me enough I ended up buying other tanks not HAUS brand. In a short time I move on to 510 box mod type batteries, and sub-ohm tanks. But that's a whole other class of vaping from this simple pen style, so comparing the two is apples and oranges.
Overall, the HAUS stuff works ok. It did get me started and off the analogs. I still have the batteries I keep around for backups, and they seem to be well built and work pretty well. The tanks are junk in my book, but other and much better tanks are available pretty much anywhere vaping supplies are sold, and are not much more than the HAUS brand, if at all. I got an Aspire CE5, a tank I really like for E-go batteries, for $6.99 from a local vape lounge. The only downfall is with only 650 mah, the battery won't keep up with a long day of constant vaping without needing charged. But you get what you pay for, right?
As for the juice, at Wal-Mart at least it's a little overpriced, 10ml for $7.99 or so. Compaired to local vape shops, that's not too bad. But there is a tobacco shop/gas station near my house that sells the same size for $4.99, and have many flavors and nic levels. HAUS has like 5 flavors, and all are 24mg (2.4%). I will say I did like the tobacco flavor they had, but I can't speak for the others, I didn't try them.
If your looking into starting vaping, it's a quick, somewhat cheap, trip to Wal-Mart to see if it's for you. If it's 3am, your away from home, just broke your vaping rig, and need some nic NOW.... it's a solution. But may be a bit steep for a short stop gap. Really I think this is just a great way to find out if this is for you or not.
