My thoughts on part 2:
Test strips: do a check using strips for both meters. I'm pretty sure that it will be OK , it is only in the last 4or so years that the meter companies have been forced by legislation to fix the meter in either mmol or mg/dl. Until then y.ou could change them from one to another
Certainly with one touch strips it is possible to use 1 touch strips from a French pharmacie, in a meter sourced from the UK, the UK meter is fixed in mmol, mg/dl are used on 'French' meters
French meters cost so much because of the health service system. Meters are available on prescription. one every 4 years, guarenteed to be replaced quickly by the manufacturer. All presciption products have a price fixed by the government, all models cost the same. There is no competition to get custom, no freebies either and a very small choice of models.They have to be governmnet approved, and theres no incentive tosubmit more than a couple of models for approval. (the fixed price has actually gone down slightly in the last 5 years but the companies seem to have negotiated a very high price).
I' m somewhat surprised you could get compact strips, the only 2 accu chek models in France at the moment are the nano and the performa , strips are available for the 'go' as people still have it. . The official French price for strips is €39.40 for 50 .
