I love mine! Mind you, it's my first and only ever pump, so I've nothing to compare it to.
Yes the handset is quite slow, but it's not a deal-breaker.
I've never knowingly had a bubble.
Pump battery life is weird - shows 100% for weeks, it seems, but once it starts to show 95% it counts down very quickly. Handset charge lasts for days in my experience - that part is rechargeable, but the pump battery itself is an AAA battery.
I love that I can do everything from the handset (although now I'm more confident and therefore more gung ho with it than I was to start with - sorry, I mean
au fait - I now often just use the buttons on the pump for setting TBRs or doing a pre-exercise bolus or whatever) so I don't have to constantly fish out the pump.
I've had a couple of cannula fails but only where I've been daft enough to put it in my most-injected and scarred areas of my tummy! These days I use the back of my spare tyre. I use the Flex cannulas and insert them with the Flexassist gadget that I got with my starter kit.
I love that the cartridges are pre-filled - no mucking about.
I love the look of it. Where the hosepipe comes out of the pump it looks really really smart - this sounds completely daft but I'm not keen on the look of the - how can I put this - hole where the hosepipe sticks out on most other pumps! If that makes sense....
I flipping LOVE my Insight pump. It's a brilliant piece of kit.
