Ms Hedi, I hear ya about the family here. Always helpful, always supportive. Keep trying on your convert. I had been trying with my friends from Florida for over a year now. They never even wanted to try before but this time when they said they were willing, I ordered up some carts that were similar to their brand. I figured if they would like it we could order up some devices. Well they were very impressed and not wanting to wait for an order to ship I gave them the ones I had. Like I said earlier they are longtime friends and I have no problem sharing. I think everyone here knows they made the right decision to switch, we just have to be patient with the converts. Good luck and enjoy the journey.
