I have no experience of the Combo and have used the Insight (my first pump) only since October.
I'm very, very happy with it. I love that I don't have to fiddle with the pump itself and can control everything from the handset. My pump is tucked away out of the way, and every time I need to 'do' anything I use the handset - which is the blood glucose monitor as well, and looks not very different to a mobile phone - touch screen and everything.
Downsides - the handset does take a while to do its thing - so after testing, for instance, you input your carbs and it does the calculations for you based on your own ratios which it's been programmed with when you do your pump start, and it does take a few moments to go through the stages. That's the only complaint I've got, really, and it's not even really a complaint - it's just that for instance it's a little bit slower than my phone (and I'm very impatient as a rule anyway).
As I say, I'm very pleased with my Insight. Wouldn't swap it.
Hope this helps!
Edited to say -
@azure you and I were posting simultaneously - it all shows how very different we all are - LOL!
