I like the app interface Great, but the monitor unit itself has several very annoying ill-conceived, seemingly very basic issues that are making me want to sell my unit as used and seek another option for the ketone readings, despite how much I like the app. The port for the tabs should face the same way as the read read-out screen— it's awkward and feels stupid to have to turn the meter around back and forth to apply blood samples to the tabs and then be able to read the results. The location of the power button on the top of the unit is very poor placement because the unit gets turned on constantly when it's it's in it's case and gets bumped or squeezed- which happens in any travel bag. I have to remove a battery to travel with it. The volume of blood needed for a read is *huge* compared to other modern glucometers requiring a lot of finger-milking to yield enough blood to study the meter. The tabs are expensive comparatively and environmentally wasteful to be individually wrapped with no alternative to purchase in bulk canisters, which I feel are also easier and more convenient to handle, rather than having to rip apart and then dispose of each test strip package. The case is very poorly designed and ill-fit. There's no small zipped net compartment to contain the used tabs (they are medical waste and not supposed to be simply tossed in regular garbage cans- so not having a place to put them means must users will just throw them out anywhere. There's no band (often a clear plastic strap) to secure the monitor in place in the case so it doesn't slide around, and no elastic band to secure the lancet pen. The case does not seem custom-designed for it's purpose, but as though a flimsy generic rectangle zip case larger that it should be was stamped with the logo. It doesn't actually provide any organization or sufficient protection for the contents. These things are very disappointing for the price-point. The Free-Style Lite glucometer is infinitely more convenient, smaller, requires MUCH less blood (thus less finger tissue damage and discomfort), is easier to handle, uses test strips that are significantly easier to handle and apply the blood drop into, functions easily in a dark situation- like a movie theatre, and comes with a well designed organized case that can be tossed in any travel bag without a second thought. Whoever was responsible for designing these parts of your meter completely lacked actual end user experience and didn't bother to research it.
