I use an Accuchek Aviva. I had used an Advantage for years, but the diabetic supply company that my insurance uses offered to "upgrade" me to an Accuchek Active. Apparently either it or I am defective, I can't get it to work. Mercifully, Accuchek sent me an Aviva which was really an upgrade. I don't know about others but I am sold on Accuchek products.
I am a member and former moderator at Diabetesforums.com. I rarely visit there anymore, when my work life got turned upside down last year I resigned as moderator and have since been too busy to spend time there.(My rare forum time is spent here and a few peeks at SOSAK.)
If you have diabetes, think you might or know someone who does, a visit to Diabetesforums is well worth your time. The style is very much like it is here. Discussion is welcome on most any topic, but by and large it is a family atmosphere. If anyone wants to know more, shoot me a PT.
