I am using a Navigator from Israel, and I know someone using one from France.
Two important things to be aware of. First, some countries use the US system of blood glucose measurement mg/dL, and some use the other system mmol/l. You should make sure you get the system you are used to since otherwise you will go crazy. Second of all they will only ship to an address in their country. Therefore, you will need a local contact to receive the package and forward it on to you. Three (sounds like a Monty Python skit now) you will get approximately zero support. No 800 phone numbers for 24/7 support. You will be on your own. Four, no discounts. When I could buy in the US I got the discount that the insurer negotiated with Abbott. Also that shipment from overseas to here is not cheap. The Navigators from overseas are the 1.5 version which give you your first reading in 1 hour instead of 10. That's really nice.
All I needed was a letter of necessity from my Doc.
However, I must stress that this is not for the faint of heart. I cannot recommend it. There is a lot of delay and aggravation and expense.
contact me off list if you need specifics.
