Mine has always worked perfectly well with both pumps once you find the exact distance to place it away from the communicator thingy, but it's finding the exact distance that is the main problem both individually at home and at the hospital, but Debbie, the nurse that does everyone's downloads has it down to a fine art by now, as do all of the DSNs.
Practice makes perfect. It would be interesting to see what other software offers though to see if I think it's better in some way or another so perhaps I'll try it if I ever have charge of another puter again - Pete won't even let me activate MS Office on this one. In some ways that's probably good because I know very well I would have instantly offered to sort the Income Tax spreadsheet you need to keep for Gift Aid purposes for a charity, for the Prostate Cancer charity we are Trustees of Yes it's the Treasurer's job but he is 80 this year and not exactly computer proficient whilst still being mentally very alert in virtually all other ways. It just rankles when we eg. collected £551 last Saturday and had all of it been Gift Aided, that would be +25% so nearer £700. We actually spent £1,480 on the testing not counting the cost of the stationery we use - it costs us virtually £15 per test. Grr!
