I'm not sure about that rjs. Looking at their website and reading what the device does, this is a big deal IMO. It last for 3 days and then your refill the insulin. It has a build in glucose meter, so no more pricking you finger many times a day to determine how much insulin to take. It gives you the appropriate amount. And you would not have to take puffs of insulin in your mouth every time you eat, which means it won't change the taste of your food. I'm not trying to be negative here, but I wouldn't discount this device.
