The piston rewind also takes longer with the Insight than it did with the Combo. It isn't touch screen like anything else you've ever had BTW - you have to stab at it hard - I find that hitting it smartly with a fingernail works best for me.
Yes the Combo reservoir has a max capacity of 315u - but if you don't need 315u in 6 days - then just fill what you actually need! ie TDD x 6, plus a bit, plus 2 or 3 cannula primes (only last 2 days on me, poor absorption) and probably 2 tube primes on top 'just in case'.
Changing a cannula takes about 30 seconds and the only time you touch either pump - is to prime the cannula once you've detached from the old un and reattached. Changing the reservoir does of course take longer with the Combo - cos you have to fill it in the first place.
There are absolutely NO advantages with the Insight over the Combo other than simply that. I don't see anything better about the menu functions frankly. It certainly isn't intuitive - and the Combo is. If you ask me the Insight is a bit too clever for its own good. Frankly if I need to change a basal rate, I doubt VERY much if I would ever be able to identify the timing of where I need the adjustment, down to the exact 15 minutes. (I know, I'll increase my basal by 0.05u/hr between 21.45 and 22.15 - that should make one HELL of a difference ..... )
The Combo is and always was - both virtually bomb proof and virtually idiot proof.
You want me to choose today ? - have the Insight back and gimme a nice new Combo. Ta !
Incidentally - you need to charge the Insight handset every couple of nights - if you EVER let it go flat - you've killed the battery completely. Also, the one AAA battery in the pump goes down to 70% and then almost immediately after dies completely and it alarms in the middle of the night, in the middle of a funeral service, job interview, meeting with important client ...... and will NOT shut up. You have to change it RIGHT NOW. With the Combo - you get a couple of hours leeway after it first warns you it's a bit low.
It works, OK - but quite honestly the ease of pre-filled cartridges does not excuse or balance out, the crap.
Oh - and Sally is correct about battery life in the Combo - I kind of used to wonder when I'd last changed em it was always that long ago, so I changed em for the hell of it usually. Always had new ones before we went on holiday - and we go for a few months when we can - and though I took spares - never needed em till after we returned home.
