Hi. I’ve been a long time Minimed user and I have to say this is the first time I’m disappointed in a device. While the 630g has great functionality, accessing that functionality is problematic at best.
The human/device interface leaves a lot to be desired.
- The surface controls are too small. I’m not a big guy. I find navigating the buttons much more difficult than prior pumps. They are simply too small. They in fact are smaller than those found on a Dexcom receiver.
- Not enough tactile feedback. The feedback from button presses is weak and doesn’t do enough to confirm an action.
- The easy bolus is anything but easy. It combines all of the above into one very difficult function to use. So much so that I find myself not using the function because I actually have to think about it more than I would when using the manual bolus.
- More button presses. Accessing any feature requires three more button presses. I don’t know about others here but I want to spend less time managing my diabetes not more.
- Sturdiness: I’ve had my pump for 2 weeks. Wear it on my belt clip. It’s already scratched.
- Design by committee. I’ve led a number of design teams and this interface reeks of a lack of vision by a singular interaction/ interface designer. Or else engineering had too much influence into the human/device interaction.
I’m in a quandary as I have this device, want the hybrid closed loop capabilities that its successor will have, yet don’t believe I can use a pump with such a poor interaction design.
