Hi, I've used all sorts of meters over 50+ years of Type 1 Diabetes, but the best one for me is an Accu Chek Mobile meter. This uses a drum of 6 lancets in the finger pricker, and a cassette of 50 test strips (both available on prescription). The great advantage of this is that you don't have to fiddle about with individual test strips or lancets, and the drum of lancets will normally last a day. The finger pricker is attached (but detachable if necessary) to the meter and you can operate the whole thing with one hand - I can test on the bus, in a queue - virtually anywhere very discreetly. And it works with Accu Chek Smart Pix software (which you have to buy - mine cost about £15 3 years ago) to download results to your computer which can then produce various charts & graphs.
I have just recently moved over to a Medtronic Veo Pump. Medtronic produce a Contour meter which can send results to the Pump wirelessly, but the meter uses individual test strips and lancets, which is a nuisance. Sadly the Accu Chek Mobile cannot communicate wirelessly with the Medtronic Pump (different manufacturers!) but I still use it and manually post the readings to the Pump.
