mCig Electronic Herb Cigarettes

About two years ago I found mCigs online and fell in love with the concept of the business. Basically they're an electronic cigarette that can be charged with a USB charger. They can be used with loose-leaf dried herbs like pot, waxes, and oils. I bought four mCigs and loved them. I purchased them for $4.00 each, but now I can't find them anywhere (except eBay for $35.00). It's such a shame, because I LOVED their product and they seem to have vanished. They were a small start-up company when I discovered them, but I assumed they would have grown. Seems like they vanished instead. Has anyone else heard of their products or tried them?

Here's the eBay listing I found to one of the last ones available on the internet.

I am so sad they've disappeared! They were definitely my favorite thing to smoke out of.
