Epson Runsense SF-810 - User Interface and Experience
Overview
The Epson Runsense SF-810 is a GPS and heart rate monitor designed for runners and fitness enthusiasts, and its user interface is relatively straightforward, though it has some notable aspects and limitations.Basic Operations
The SF-810 features a simple and intuitive interface with a limited number of buttons. It includes a Time screen, Measurement screen, Settings screen, and History screen. The buttons allow you to perform various functions such as starting heart rate measurements, switching between screens, and adjusting settings. For example, a short press on the button can start GPS positioning or turn the light on/off, while a long press can access the Settings menu or display the time screen.Data Screens
The watch offers four customizable data screens, each capable of displaying up to three data fields. These screens can show real-time data such as heart rate, pace, distance, split and lap times, altitude, and stride. You can switch between these screens by pressing the ‘DISP’ button or by tapping the front of the screen.Starting a Run
Initiating a run is straightforward. You press the upper right button to start searching for GPS satellites, and once connected, you press the button again to begin tracking your run. This process is relatively simple and does not involve complex menus.Customization and Settings
Customization of the data fields and screens can be done via the mobile phone app or the watch itself. The mobile app allows you to configure target paces, automatic laps, and other settings. However, the app’s user interface is often criticized for being slow and modal, requiring multiple interactions and waits.Upload and Syncing
Uploading your run data can be a bit tedious. Using the mobile app, you need to stop the run, place the watch in Bluetooth sync mode, open the Run Connect app, and follow several steps to upload the data. This process can be frustrating if any steps are missed. In contrast, uploading data via a computer using the USB charging cradle is much simpler.User Experience
The overall user experience of the Epson Runsense SF-810 is mixed. While the watch itself is easy to use for basic functions like starting a run and viewing data, the associated apps and website can be cumbersome. The mobile app and website are often slow and lack a clean user interface flow, which can be frustrating for users accustomed to more seamless experiences from other fitness trackers.Additional Features
The watch includes features like vibration alerts, indoor mode for training without GPS, and water resistance up to 50 meters. These features enhance the usability of the device in various conditions but do not significantly impact the core user interface.Conclusion
In summary, the Epson Runsense SF-810 offers a simple and functional interface for basic operations but falls short in terms of app and website usability. While it is easy to start a run and view data on the watch, the process of uploading and managing data can be more complicated.

Epson Runsense SF-810 - Performance and Accuracy
Overview
The Epson Runsense SF-810 is a GPS running watch that stands out for several key features, but it also has some limitations and areas for improvement.Performance and Accuracy
GPS Accuracy
The SF-810 is praised for its solid GPS accuracy. It quickly locks onto GPS signals and maintains a reliable connection, even in various environments such as city runs, long runs, and treadmill sessions. There are no significant issues reported with GPS accuracy, making it reliable for tracking distance, speed, and other GPS-related metrics.Optical Heart Rate Monitoring
One of the standout features of the SF-810 is its optical heart rate sensor, which is highly accurate. Developed in-house by Epson, this sensor works well most of the time, although it can be affected by external light and cold weather. It typically takes about 30 seconds to acquire your pulse, and once locked, it provides consistent heart rate data.Battery Life
The battery life of the SF-810 is impressive, offering up to 20 hours of GPS and optical heart rate monitoring, and up to 24 hours with GPS on but optical heart rate off. This makes it suitable for extended running sessions without the need for frequent recharging.Data Customization and Display
The watch allows for customizable data pages, with up to 4 pages and 3 data fields per page. These can be configured via the mobile phone app or directly on the watch. The tap-screen control, although sometimes too sensitive, enables easy switching between data pages during runs.Limitations and Areas for Improvement
Software and Setup
One of the significant drawbacks is the clunky and time-consuming software setup. Users have reported difficulties with the initial setup, firmware updates, and transferring data to other sports analysis software like Strava. The supporting software, documentation, and procedures are often criticized for being cumbersome.Swimming and Water Activities
The SF-810 does not perform well in swimming activities, particularly in open water. It fails to track GPS and heart rate accurately in such conditions. There is no functionality for tracking lap distances in pools or open water, and it is not designed for swimming or triathlon activities.Intuitive Use
The menu system of the SF-810 is not very intuitive compared to other watches from brands like Suunto, Polar, or Garmin. This can make it difficult for users to find and use certain features, even though the functionality is there.Additional Features
The watch lacks some advanced features that are common in other high-end GPS watches, such as multisport mode, training calendar functionality, and the ability to download custom apps. It also does not support ANT connectivity for heart rate straps, speed/cadence sensors, or power meters.Conclusion
In summary, the Epson Runsense SF-810 excels in GPS accuracy, optical heart rate monitoring, and battery life, making it a solid choice for serious runners who prefer wrist-based heart rate monitoring. However, it falls short in terms of software setup, swimming capabilities, and intuitive use, which are areas that Epson could improve upon.
