Pros
- 1) An appropriate size (one that is not cumbersome), at least for the hands of a man. 2) Low in weight, to the point where it can hardly be felt on the hand 3) An excellent amount of time that can be used from a single charge: between 25 and 27 days while using the "just watch" mode and turning off notifications from applications. In the standard mode for recording GPS tracks, the consumption is 3-4% each hour (with a maximum of 30 hours), however in the economical option for recording GPS tracks, it can take up to 60 hours. 4) I tested the accuracy of the heart rate monitor by using a different heart rate monitor that included a chest sensor. It performed very well. 5) In the training mode, you have the ability to configure the screens (the number of screens, the number of counters on each screen, and the composition of the counters on each screen). 6) There is an option that provides constant night illumination, which is helpful for practicing during the night. 7) Practical and functional mobile application for Android-based smartphones 8) Immediately locates the location on the GPS and writes down the GPS tracks with precision 9) In addition to the graph, there is both a barometer and a barometric altimeter that both function well; the altimeter displays the number of "floors" you have climbed. 10) the screen's backlight is functioning correctly. 11) there is a thermometer (caution: you must take the watch off your hand in order to get accurate readings from the thermometer) 12) the capacity to upload performance data to a variety of internet services, including Strava, Training Peaks, Relive, Final Surge, Runalyze, and Apple Health 13) the capacity to upload music in the following file types: *.fit, *.tcx, *.gpx, *.kml, and *.csv 14) the option to build a training schedule according to one's own whim (this isn't something I use, but it could be useful for athletes). 15) there is no touchscreen and the possibility of issues related with using one 16) a transreflective display, which makes it possible to read the screen even when it is directly exposed to sunlight 17) There are profiles available for a variety of activities, including one for the room that contains a "exercise bike, etc." 18) the availability of a pedometer that is in good functioning order (there is a margin of error, as is the case with any pedometer, but it is reasonable) 19) There are notifications from various programs, but I do not make use of them because they are not required and I want to conserve energy.
Cons
- 1) [FAR AND AWAY THE MOST INCONVENIENT] Every single interchangeable dial that can be used in the "just watch" mode has a "defect" of some kind: a) a design that is too basic, unsightly, and cumbersome; all of the dials are, to a greater or lesser extent, awkward; there is not a single dial that is both elegant and functional at the same time (so that all indications can be seen and understood without difficulty); b) the numbers of the readings are either too little or too huge, or parts of the readings are not displayed. c) the majority of replaceable dials do not display the month (they only display the day of the week and the day of the week). d) There is not a single dial that can be interchanged that displays both the current date and a month (particularly a year), nor is there a dial that displays both simultaneously. c) on many dials, a typeface for the numbers that was not successful (too curved tails and sticks; as a result, the digits 5 and 6 look visually identical). 2) [FAR AND AWAY THE MOST INCONVENIENT] The readings on the pedometer cannot be reset, nor can they be connected to the beginning of a workout. The number of steps taken in a day is meticulously tallied from midnight to midnight. 3) The readings on the heart rate monitor are "delayed" by anywhere from 5 to 10 seconds (I tested this with a heart rate monitor that included a chest sensor). This is a HUGELY INCONVENIENT feature. 4)[NO CRITICAL] When it comes to fastening and unfastening the strap, the stock strap is overly pliable and elastic. While this is advantageous for the purpose of pressing the monitor against the user's hand in order to obtain a more accurate heart rate reading, it makes the strap more difficult to adjust. I purchased a strap from "Coros Apex 42 mm," and although it is more difficult, the fastening process is now much simpler. 5) [NON-CRITICAL] every time the application on a smartphone throws a request for permanent work in the background (I deny the request every time, but it does not remember the choice I make), 6)[NO CRITICAL] The application on the smartphone cannot be closed; instead, it will continue to run in the background, where it will remain until it is eventually unloaded by the operating system on its own. 7) [UNCRITICAL] not a very convenient solution with a spinning wheel button (it works fine in general, but in my own opinion, simple buttons are more convenient). 8) non-standard charging connector; a unique cable is required to charge the device. 9) This model does not feature a mode for alpine skiing or snowboarding; therefore, you will need to locate "circles" manually. 10) [EXTREMELY IMPORTANT] In the year 2022, there will be no formal guarantee or service (everything will depend on the integrity of the sellers).
