Then speak to your DSN before your appointment and let them know how frustrated you are with your model of pump.
I had an Insight, hated it, spoke to my DSN and explained why it wasn't suitable, and then I got a different pump model - ie not an Insight.
I've been pumping for 12 years and would never want to go back to MDI, but that one pump drove me mad. I've had two other pump models and they've both been fine.
If you don't like pumping then go back to injections, but do be sure it's the pumping you don't like rather than the pump. If the Insight had been my first experience of pumping,,I'd have been very down too.
