The right/best pump is the one that’s right for you
@Lily123 Other people might have different needs and different priorities and preferences.
Think about your lifestyle. Write down the features of each pump and circle anything worrying or anything extra-good. Remember too that cannulas are very important and often neglected. It’s no good having the world’s most advanced pump if the crucial interface with your body (the cannula) is c**p or doesn’t suit you. Personally I’d never go for a pump which didn’t have a choice of cannulas, and I’d never go for a pump that had cheapy or dodgy cannulas. Make sure your chosen pump fulfils all the criteria: good pump for you, good cannula choice, good customer service.
I’d choose the Dana out of those, as you probably guessed. You can get a cheap Android phone if that’s an issue. I don’t loop with mine.
