I've certainly been more pleased with other devices I've used in the past. Opening the test strip packets is WAY more difficult than it need be. And it took me QUITE a while to figure out which side to open so that I wasn't having to touch the side where the blood goes! Not being able to order the testing strips on Amazon made ordering just glucose testing strips quite expensive once I stopped trying to maintain ketosis. I also found that the device was inconsistent in how much blood would be needed for it to register, which led to multiple pricks and testing strips some days just to get one reading. For me the online recipes were somewhat useless as I have nightshade and dairy intolerance--too many of the recipes include dairy (seems to be a primary staple for most people on keto diets). But that's not your fault, just food for thought. Moral of the story is that I would not recommend your device to anyone looking for a glucose/ketone monitor. I've had a much more easier and cheaper experience with other monitors.
