As a Type 1 you should be entitled to have a bit of a say about your meter because of the large number of tests expected of you.
I find the Mobile to be invaluable as it's much less bulky than a kit and you can do the whole thing stood up, for example in a shopping centre, without having to faff about with strips.
You should get in touch with your hospital clinic if you're not happy about having your meter changed by your GP. They should support you to keep the meter if you feel strongly that another meter might not suit your needs or discourage you from testing.
