I love to see how what I eat effects my blood sugar. The accountablility is priceless. The data is sometimes confusing and not always able to predict. I wished it would tie into my Fitbit or Cronometer so I didn't need to log my meals twice. I wished there was community to ask questions. What size of spike is ok? How long is too long on a spike? etc. Why does the device cause huge bruises and pain, is this preventable? I like how there is a longer grace period than before. Overall I really like it!!
