From the videos on that site, the pump looks too big to me, I'm used to the small canulas on my Paradigm Veo and that would just get in the way and probably be uncomfortable. The Bluetooth controller is a good idea, and they seem to have given up on the idea of using your mobile as the control device, now opting for a combined BG meter and control panel with touch screen. It still runs the risk of some nasty so and so lifting it from your pocket though and if you don't have a spare, you're a little bit stuck. I think I'll stick to the type of pump I have for this reason alone but also because 500 units is triple what my pump has and that lasts 3 days with me, at which point the insulin is starting to go off, 7 days as 500U would give would lead people to want to keep the cannulas in for too long, risking possible infections. Not good.
