For decades, diabetics have had to prick a finger to get a drop of blood on a test strip that is then inserted into a meter to quickly display a blood glucose reading.
Then a CGM — a continuous glucose meter — which attaches to your upper arm was invented. It transmits your reading to a cellphone app. It still has to slightly puncture the skin when first applied.
Now, miracle of miracles (if you believe their ad) comes the Pryxo non-invasive blood glucose monitor. You simply stick your finger in it, and five seconds later the digital display shows your reading.

Our advice, save your money. You will probably receive a pulse oximeter to give you your oxygen saturation level and heart rate, not a device to measure your blood glucose. No consumer device has yet been invented and made widely available that doesn’t involve some penetration of the skin.
