We have been using a fleet of these devices of 15 pieces for the second year. Auto-ate firmware is enabled (they come out quite often). Someone wrote in 2022 that the devices freeze - we have not had a single freeze or failure in 2 years. Someone wrote in the shortcomings that the display does not go out - everything goes out, you just need to go into the settings and specify the brightness for the standby mode (Settings-> Options-> LCD screen-> Active backlight time). The device is from the series, set it up and forget it.
