A little high priced for unproven technology when brands like Exped sell a similar sized pump that's even more "sanitary". It may well have it's virtues, they're just not bringing up the ones that I'm interested in such as weight, R-value, or durability of the valve. Besides, if I'm gonna lay on the porch, I'll use a chair. Not strong selling points.
It may just be a case of finding their place. Easier to do if the product is out there where other innovators get a shot at it. Kickstarter is great for that.
