I mainly use my AccuChek Combo meter (which is like the 'Expert' but has added Bluetooth and also acts as the remote control for my pump) with 2 x Nano's as back-up.
Plus I already had a really old One Touch Ultra, and a newer Ultra 2 which was in use pre-pump. I also had a One Touch Ultra Easy I blagged off Lifescan a while ago (a metallic red one, yay!) which I wanted for little handbags to save having to take a portmanteau to eg weddings, and I now have a new one of them as well, which my DSN really gave me as a bit of a joke as she didn't think I had enough boxes to carry at the time .... and I had a period of serious meter malfunction so she sort of let me have belt, braces, belt, braces, belt and braces ...... makes a nice change.
I get 150 strips on repeat which I can re-order at will, except it's "6 x" and when that runs out a GP has to renew it again. They do this automatically though when I put the last repeat in, don't have to explain myself to anyone. Which is exactly as it should be!
