Easy to use. It is easy to track and able to add reads manually. The only reason I'm changing my rate from 5 stars to 2 stars is because while I find this to be a good product, easy to use and read results from home, for whatever reason it's not syncing with my doctor's office. Dr Reetu Singh is my Endocrinologist, and her office is the one that provided the OneTouch Reveal. I hope this can be fixed so that she reads my numbers from her office. Thanks.
