Yes, it certainly is different - nice and compact. If I read correctly,it is vaporware unless they receive $25,000 in advance sales within the next few weeks. I would feel more comfortable with a container I could use more than three times.

I could find no mention of capacity. By my crude calculations, the large size holds roughly 500cc, half a liter. I would prefer something that could sterilize more than one and a half liters of water in an emergency situation.
