This is one of my favorite models of fitness tracker. Ive been balling something that they think might be POTS and Ive had issues with my oxygen going into the 70% at night. I like that this has a oxygen feature. I wasnt able to check it against the one at the Dr, i forgot to take it. So i do suggest to get a baseline and compare it to a professional one while at an appt, just like uou do woth a scale to make sure they match up.
Its easy to charge and fit comfortably
