Amazfit Band 7 Fitness and Activity Trackers and Smartwatches, Heart Rate, SpO2, Sleep Analysis, Amazon Alexa Built-In, 18-Day Battery, Black

I have used this for only3 weeks.So far it is really good. The battery life is great 10 days with continuous use. Step counting and sleep recording seems accurate The notifications of messages and phone calls are good. It serves the purposes I bought this watch for. I don't use this for HR or other Monitoring so do not know of the accuracy.I hope this watch continues to work as it is now. Then it's a great watch and price.I wish the watch had better options for display faces. Most of the choices are loud and colorful my preference is simple and elegant .

After several false starts when the band would not sync with the app, it works well. It's a little tricky to put on without being too tight or too loose. I use an elliptical exerciser, but the band does not support it. It would be better for running, cycling or walking. The sleep info is not always entirely accurate, but it gets close. The one touch heart monitor is helpful. It counts steps fairly well, though it overcounts my elliptical steps. Customer service is unusually good, clear and personalized, a real plus. Charges quickly. I don't wear it in the shower so I can't say if it is truly waterproof. Overall, I am happy enough.Update: At week 7, the band unlatched by itself and the crystal broke when it hit the pavement. Again customer service was exceptional, replacing the band and paying for shipping the old one back. Though the new band has unlatched when bumped once or twice, it has not been a big problem. I added a matching small rubber band near the latch several weeks ago. It seems to help.

UPDATED 12-31-2020 [This a a real review]Set up is easy as you download the Zepp app and pair the watch to your bluetooth, then register to sign in. The little band is a bit hard to fasten on your wrist at first as you get used to it, and I have had it come off in bed and once just in everyday use possibly because it wasn't fully secured but more likely due to catching the closure button on something. The read outs are easy to use although the instructions and explanations of functions are somewhat vague. The measurements to input some manual things like blood pressure, body temperature, etc., are only in UK measurements so you have to convert the numbers. Hopefully they will change this for imperial measurements, too. In your profile the standard measurements can be set to imperial or UK so there is no confusion seeing your readouts on your band or in the app.The band itself provides the ability to change around the menus so those you're most interested in can be scrolled to up or down, left or right, quicker. You can rotate your wrist toward you to activate one of the chosen 45+ provided watch faces (the automatic watch face reveal can be scheduled to turn off when you're sleeping) or you can just tap the lower part of the face and the length of time for viewing can be changed, too. Then you can scroll the menu so that side to side brings up Alexa/ Notifications in one directions and Weather/Heart rate in the other as they repeat in a circle. Pulling the screen down reveals More/Workout/Weather/Events/Breathing/Stress/Notifications/SpO2/Heart Rate/PAI/Status before returning back the the watch face.MORE gives you options: DND/Alarm/Camera/Music/Stopwatch/Timer/Find Device/Silent/World Clock/Band Display/Settings. When you use the app to download one of the 45+ watch faces (band display) at least five remain as a choice in the Band Display section for quick change. Settings allows further adjustments to the watch face use and ability to reboot.WORKOUT: Outdoor Running/Treadmill/Cycling/Indoor Cycling/Walking/Elliptical/Rowing Machine/Yoga/Jump Rope/Pool Swimming/FreestyleWEATHER gives you current local conditions and forecast for the next six days. Temperature/Humidity/Level/QualityEVENTS are reminders of upcoming things you input by speaking into the watch.BREATHING is an exercise to calm and relax you.STRESS measures your level between 0 and 100 based on heart and pulse ox and other factors.SPO2, also known as oxygen saturation, is a measure of the amount of oxygen-carrying hemoglobin in the blood relative to the amount of hemoglobin not carrying oxygen. The body needs a certain level of oxygen in the blood or it will not function as efficiently. In fact, very low levels of SpO2 can result in very serious symptoms. You can quickly test here to obtain your SpO2.HEART RATE measures the beats per minute, BPM, and can be set to check this periodically or manually here.PAI is the physical activity intelligence that takes data to provide a number up to 100 showing your activity level, and this number climbs as days pass and it automatically computes the number. You can quickly do a manual test here, too, following the on screen directions.STATUS shows your steps, calories used, distance walked, idle alerts (if so set), and previous days step counts.ALEXA is a nice addition and works well with responses in text format. It is not necessary to say the name, Alexa, just scroll to menu and input your command or question. I often use my Band 5 to turn on/off or command smart lights, plugs, and smart light strips. I can walk in a room and command a light, or change the temperature on the Ecobee Thermostat, if so desired. Very quick responses to questions and computations make this a very nice feature.NOTIFICATION work very well and promptly show on the watch face to be easily read, and can be scrolled if a long message is received.BATTERY LIFE so far seems to be on average around two week at least before a 2 hour charge is necessary using the round magnetically attached plug and short cord. I charged mine after 12 days at 17% remaining charge so it would have gone a full two weeks before going dead.CONCLUSION. There is a lot to explore and I have continued too use a Fitbit Versa for steps and distance as well as another app, MapMyRun, to plot the GPS path and distance. I have not gotten the Amazfit Band 5 to accurately give my distance and show a GPS plotted route like the MapMyRun app provides. However, the step count is more accurate. It may well be that the Versa and MapMyRun app are interfering with the GPS so that Band 5 cannot calculate this properly. I will experiment in time and work with developers to see if a solution can be found, but it's not a big problem for me. MapMyRun's browser data and history with routes is quite satisfactory and I have found history is available when you use the icon in the top right of the Zepp app and see under Exercise Data the Exercise Record where period of time can be selected and individual dates show full data (again, the routes shown and distance/steps are wrong, so far, and still experimenting with this error). The Versa serves as a watch and notifications I can easily read. Band 5 does not provide the ability to switch functions while using the Workout function, but it does show notifications. So you cannot use the Band 5 for anything else during work outs, if I am not mistaken. Note that outside in the sunlight it is very hard to read the screen, however, unless you turn the brightness up under setting to maximum from the default applied to conserve battery.Overall I am very pleased with all the data, including the SLEEP DATA it provides for helping the wearer to better health. A beta Breathing tracking function can be set to check for problems while you sleep and it scored me 99 out of 100. As you turn on things like this it does warn of extra battery use. It could be, and probably will be tweaked so the wearer can more customize it to the wearer's own needs and life. For the price, it is great, and now there is an inexpensive compatible replacement band assortment in 15 colors for easy change to coordinate with your daily wardrobe. As I wear and use the Band 5 I may add more to this review.UPDATE AFTER DST: Strangely the sleep record is not recording on the date it should and runs a day behind. Reporting errors or suggested improvements seems to go unnoticed as the step count is still showing the miles lower than actual, e.g., 3 miles is shown as approximately 2.5 even though the steps are correct, so the stride distance is wrong and possibly due to the GPS not working correctly with my Moto G6 Plus watch. No fix so I depend on my cell's app, MayMyRun, to accurately record this for me.

Honestly would not recommend this watch at all.First, the heart rate monitor and sleep monitor are very inaccurate. I compared the heart rate measurement several times during various levels of rest or exercise with the readings from my blood pressure arm cuff. While I was expecting some inaccuracies maybe plus or minus a few bpm the watch would report 90 bpm when my blood pressure device read 130 bpm and when my blood pressure cuff read 90 this would often read anywhere from 70 to 140. Sometimes tapping the measure button would read 130 and then 2 seconds later read 80.Second, the device has a feature where if you press and hold the screen you can quickly change the watch face. This is extremely annoying as the screen is extremely sensitive and I found if my coat sleeve slid forward it would trigger it, or if I crossed my arms it would trigger it, or just resting my arms in my lap would trigger it. There is no way to disable this feature and with how sensitive the screen is to any kind of touch from anything it gets very frustrating very quickly.Finally, most of these issues could still be overlooked to an extent but after having it for only about four months the screen popped out on me and was dangling by the ribbon cable connecting it to the circuit board. I carefully set the screen back in place and glued it back in using a compound that would seal it from moisture so it wouldn't get damaged further but that didn't last long. I glued it once more with some heavy duty glue but that also failed after about a month. The third time it popped out and I glued it back in the screen had solid white vertical lines so I popped the screen out and discovered parts of the wiring on the ribbon cable had cracked due to the screen hanging freely by it. Now, with no functional screen whatsoever I am unable to turn the device off at all since there is no physical way to turn it off without using the screen. Thankfully I was at least able to turn my alarms off through the Zepp app so it would stop buzzing when sitting on my desk.Overall, this thing is cheap garbage and I wouldn't waste a penny on it. Only reason I give it 1 star is you can't give it 0 and my mom likes it cause she has metal allergies and this is the first fitness tracker she's found that does not have any metal against the skin.
