Premium Fitness Tracker with 24/7 Heart Rate, Blood Oxygen, Blood Pressure & Sleep Monitoring | 5ATM Waterproof Activity Tracker with Step Counter & Pedometer (Includes S & L Bands) - Ideal for Running, Swimming & Daily Health Tracking

I went back to one of these smart watches after about 8 months with an iWatch. The iWatch now loses charge before the end of the day; this watch (much, much cheaper btw) keeps its charge for days. I had one before, but lost the charger cable & replaced it with an iWatch. Disappointed in iWatch. I'm only keeping it charged and on the window sill for when I need to use it to locate my cat via AirTag (you need more than one Apple device going so the AirTag can triangulate location.) This Health Fitness Tracker watch measures all my steps throughout my active day; no need to reply to a message "It looks like you are taking a walk. Record activity?" With this watch, it simply measures my steps, heart rate, blood oxygen level and blood pressure through the day (although I would not count on the BP too much, however it has been pretty close to my cuff BP much of the time so far.)
