This watch accomplished everything I wanted it to accomplish and more. I believe it was an excellent buy for this price point and definitely recommend it. I've had a number of other similarly priced watched in the past and each one seemed to have some area where the software or a function was lacking. So most of what I will mention are things I was pleasantly surprised by or have found lacking in other products that this has. I've had the watch for more than 2 months.APP - Right away it will prompt you to download the "Mi Fitness" app (Xiaomi Wear), which has a pretty good interface and settings, but I found that the watch also connects well to the "Zepp Life" app (formerly Mi Fit) and this app gives the watch a few more functionalities that I wanted. The Zepp Life app connects to Google Fit without a third party app as well as allowing you to reply to messages (from a bank of up to 10 customizable messages or with emojis (find in 'Fast Reply Management' under 'Notifications and Reminders' in the app), and it allows you to remotely take pictures by clicking your watch. I think the notification reply feature is worth the switch.HEALTH - It has over 100 workout modes (including chess, esports, and foosball), but does more data for the more common ones. The workouts have been pretty accurate it seems and it does pretty good at doing continuous monitoring of heart and calories and speed and whatnot. If you choose an outdoor workout it will take a second to connect to your phone GPS and then you can start, but you don't have to open your phone at all. It has done a pretty good job with tracking swimming and I did not have trouble exiting the locked mode for swimming.Note that the watch does not have continuous heart monitoring except when in a workout mode (the most frequent otherwise is every minute), so if you forget to start a workout on your watch then it probably won't be very accurate in calculating your heart rate zones during that workout. But the watch will record 'light activity' or 'slow walking' among other things without you doing anything if you take a closer look at your step count. - Blood oxygen and stress measurements require you to be pretty still while measuring, so even if you have the setting where it is supposed to measure every few minutes it most likely won't unless you are very still. It mostly measures when you are asleep. - Most watch companies have some formula for basically showing how active you have been recently. Xiaomi has PAI (Personal Physiological Activity Indicator), which takes all of your data and your personal physical data (height, weight, gender) and gives you points based on how much activity you have done in the last week. It adapts to what it knows about you and makes it harder to gain points the fitter you are. I like it, another fun thing to track. - You can also see that it calculates your VO2 Max, which I don't know if you can trust, but it fun to compare against your past self; and it shows your 'workout load' for the past week, which shows if you are exercising an amount that will not have much impact on your athletic ability, or if you are doing too much and are likely to cause fatigue or injury, or if you are in the green zone of growing athletic ability. It's another fun measurement.BATTERY - The battery is very good. When I first got it I ran a few tests: 1. The battery lasted 7-8 days when I used it at medium functionality (1-2 short workouts/day, smart heart monitoring, and only manual stress and blood oxygen measurements, no Always on Display) 2. The battery lasted 4 days when I turned pretty much every feature that could drain battery on (I didn't turn AOD on but made the tilt-to-wake more sensitive) 3. There is a battery saver mode that only records steps and basic sleep information that I didn't try, but I imagine it will reach the 14 or so days that they claim it can reach.Now I have most of the features on and I just charge it for about 20 minutes when I take a shower each day (it recommends keeping the watch away from heat) and the battery stays in the 80-100% range.I didn't find the sleep breathing quality (beta) feature to be very helpful, but it does seem to give a good drain on the battery (it uses the blood oxygen levels somehow; it might be more helpful if you are older and have worse sleep).OTHER FEATURES - See the picture for all the apps on the watch. - I do like that you can set and change and add new alarms all from the watch. I also like that there is a 'smart alarm' function you can turn on that will wake you up a little before your alarm if it senses that you are in a lighter sleep stage. - You can control the media playing when you are in workout mode, and you can lock your screen on workout mode to prevent accidental touching (automatically does when swimming). - There is a find my phone feature that I have found to be helpful. - There are plenty of watchfaces to choose from and you can even upload your own picture on some of them. Some of the watchfaces allow you to customize what information you have on the screen. - I've also had no problems in staying connected to the app. It always delivers notifications and syncs easily with the app. - It has all the other functions that you might expect a watch at this price range to have.ISSUES - You should note that the device does not have a light sensor on it so it will not automatically adjust the brightness for you, and for some reason you have to dig through settings to be able to change it at all (which is hard to do if you can't see your screen).I don't usually need to turn the brightness up, and actually wish the screen could be less bright at the lowest setting, so I just changed my background to a darker one and that helped.
