I love the compactness of the Contour USB.
I love the fact that I can just plug it into a USB port and upload the readings.
I don’t have to buy any additional hardware/software to get it on the computer.
Dislikes:
The software is very limited in what it will do! I would like to enter my meals, my exercise activities, my A1c, etc. I don’t see how to do it with their software. However, all this is mitigated by the fact that the data is stored in a SQLite database that is on my hard drive. And, there is nothing stopping me from writing my own GUI front end to enter all that stuff and display it what ever way that I want!
