“The GK+ Blood Glucose & Ketone Meter is wonderful assurance to whether I am in Ketosis or not. The Meter is nicely designed, and integrates beautifully via Bluetooth with the equally nice phone app. Everything you need to test is conveniently stored in a small compact protective case. This is a great value and like I said its nice to know when I'm in ketosis, or when Ive fallen out of it... (stupid Okctoberfest... lol)”
