Hi
@Smammer , and thanks
@Jaylee for the tag,
I didn't have a choice of pump (was a bit miffed at the time!), and had read a lot on here about people's experiences with the Insight. It's the only pump I have had, and I absolutely love it!
The convenience of NOT having to fill a reservoir with insulin and sorting out any bubbles is fantastic! A cartridge lasts me for 5-6 days, and it's really easy to change. Due also perhaps to the fact that it has a cartridge rather than a reservoir, the part where the hosepipe comes out of the pump is very sleek, making the actual pump look and feel very attractive - I know it's not about the 'look', but I'm shallow like that!
Dealing with a cartridge change is straightforward. I make sure I take my NEXT cartridge out of the fridge at every cartridge change, and pop it into the zippy case I carry round with me (it's a Joe's Small-in-one - highly recommended) so it's ready to be popped in immediately when it's needed. A cartridge holds 160u, 14 of which (in the case of a 70cm hosepipe, which is my preferred size) are used to fill the hosepipe, and 0.7u (depending on type and size, obv) to fill the cannula. So that's 145-ish units available per cartridge (as I don't think the unit counter counts what's in the hosepipe when it says the cartridge is running low - I might be wrong on this though). The fact that it holds this amount might be a faff for those on more insulin, but it suits my TDD of between around 22u and 28u perfectly.
I have had two (minor, non-dangerous, just annoying) issues with my pump (the fabulous handset's on/off switch misbehaving) and Roche customer services have been amazing.
I LOVE MY PUMP!
