The KetoMojo device and strips I would give 4.5 Stars. The loss of a half star is simply because I find opening the packaging countaining the strips more difficult than it needs to be. Where I am disappointed is the App. I find it too limited and too rigid. I wish I could do more of what I want with it instead of having the App's designers telling me what to do. I don't agree with the necessity of owning two readers for my wife and me - BUT Keto Mojo discourages this. As a result you cannot pair the reader with two separate users. This is just one of the rigid limitations of the App that leads me to rate it to 2 Stars at best. Other than that, it is a quality device, with what appears excellent service.
