The device's display is very dim and only appears properly readable from certain angles (from below). Some of the displayed data (such as current load) is not shown immediately and cannot be scrolled through as in previous models; instead, you have to wait because the system only displays data at certain intervals, rotating through multiple parameters.
The button beeping cannot be turned off, this was also possible in the previous model.
The wi-fi software that comes with the device is primarily optimized for displaying savings (unnecessarily so, since it can only handle certain currencies and fixed pricing, making it unable to display data that corresponds to reality). Accessing technical parameters requires multiple steps and is complicated to navigate. For example, the battery charging current can be found in a closed accordion on the secondary screen, in an extra step after scrolling the page—yet such data should primarily be displayed on the main interface. Overall, the device's capabilities are adequate, but from a UX standpoint, it represents a step backward in every respect compared to my previous EASUN model.
