I love the ability of the biostrap to measure arterial elasticity and does a better job than the oura ring at measuring O2. However a few things can be improved. The charging dock is of poor quality. the cable does not stay in the charger and needs to be pushed in each time. The biostrap itself does not sit securely on the charger and is easily tipped over, unlike my apple watch which has magnets securing it. The biostrap has straps that are too long and made of a material with too much friction to easily put on the wrist. I find it too much a hassle to use when compared to my apple watch and oura ring. For now I cannot recommend the biostrap to my patients. The software does not sync as well at times with my iphone. The battery level should be displayed on the main page and send out reminders to charge before bed if there is not enough battery.
