Best Fitness Tracker with Heart Rate Monitor, Sleep Tracking & Step Counter - IP68 Waterproof Smart Watch for Men & Women | Perfect for Running, Gym Workouts & Daily Activity Tracking

got my wife a smart watch worth 5 times more than this one, she was happy with it and encouraged me to get one as well, i noticed this one takes the temperature beside the heart rate, blood pressure, and oxygen saturation, and all the other pretty standard functions including step counting, and sleep tracking, so went for it, had a question early on, contacted the seller, super responsive, heard back within a day, and it was a real person who actually resolved my question instead of an automated reply, so kudos to customer service, i charged the watch once fully and waited to write a review until it ran out, impressive 3 weeks and half, that's with daily wearing, and at least once a day checking my temperature, heart rate, blood pressure, and oxygen concentration, i know smart watches are not medical devices, no expectation of medical degree accuracy, and i don't have any chronic conditions to challenge the tracker, from my first month/daily experience, very rarely i would get a crazy value, it has only happened with heart rate, as if i'm tachycardic when i'm not, i measure it again, i get a normal number, i believe the temp is probably the most useful feature for me, in case i feel warm and think i have a fever, want to comment on the 1 button easy operation, it's not really a button, but like a small rectangular area below the screen which has a really good resolution, my son has a toy smart watch with a bunch of games but low resolution, so a high resolution screen is good! short press the rectangle, the watch takes you from one screen/function to another, it automatically measures my heart rate when i leave the screen on that function for longer than a second or two, and for screens with additional functions, like the screen that says "more", you long press on the rectangle to access the additional function, also long press to back out or exit, unlike my son's toy watch, this one can be turned off completely, the band feels soft and fine crafted, definitively not cheap plastic or rubber, my wife's watch uses a magnet charger on the back, i was apprehensive about this one's plug in charging that it might become loose after a number of charges, but judging by the battery's longevity and the quality bands, don't think i need to worry about it, the other thing i have liked it's the app, pretty clean and also straightforward, i can turn on and off functions on the app when i synch the watch to phone, i like to keep it minimalistic, there is a function i haven't seen on other smart watches which is named "women's health", once you input some data, it suppose to track where you are in your cycle, i'm a guy, cannot tell what it does, as connection and reconnection between watch and phone, for me it has been reliable, of course i do need to have the bluetooth on the phone, the app also requires me to have the location on, when the location is off, the app won't connect with the watch, otherwise, the watch seems to function entirely on its own once i set it up with the app out of the box, i'm still impressed by how many things this high tech bracelet-app pair can do, even though for my daily use, i got all the functions i'm interested on the watch, time, date, notification (call/text), vital signs, and more (step counting, reminders, calories burn...), in summary, great tracker/bracelet/smart watch with awesome battery power, well made, informative app, useful function, the best customer service, and stuff i haven't seen in other and older models such as temp and women's health, highly recommended, i have like it so much that i have bought screen protectors for it, one more thing, i fish, so i has also survived good couple of raining days no problem!
