I don't use the remote or the food advisor. The remote suffers from a scroll speed flaw that necessitates overshooting/undershooting frustration. Some people have become accustomed to it, especially if they like to locate the Ping under layers of clothing. I did use the remote for a few weeks and the radio frequency connection with the pump was solid. The "scroll-circus" was something that I could not live with.
I use a Calorie King mobile app on my phone when I'm out and an Excel spreadsheet dose calculator when I'm home. I dose insulin using carb, protein, and fat grams.
I like the Ping because it's waterproof, dependable, tough enough for the common every-day hazards, and their customer service responds well. I also like that the Ping uses the standard leur-lock infusion set connectors and therefore gives a wide choice of non-propreitary infusion sets.
