Has anyone used Kudos mobile payments (card swipers)?

Kudos payments makes credit card swipers for desktop and cell phones. What caught my eye is that unlike Square, Kudos is available in US & Canada. I'd like to hear feedback from anyone who has tried their products, especially within Canada. Their site states that they charge $100 per swiper (different types for mobile vs desktop) and 2.9%+20¢ per sale.
