Quality ok. Usability - here the problem is starting, problems with operation over WiFi, poor interface for debugging errors. A product for IT and automation specialists. The average Kowalski may become discouraged. You should buy a few days in advance if you want to avoid seeing a disappointed child when the parent struggles to start the device.

Everything's fine.
Patryk S. 17.02.2021 Confirmed purchase Translated review
The product is significantly improved compared to the previous versions, but also depleted of the additions that were included in the set, for example, the M5Stack Fire Kit. On the plus side, better performance, touchscreen and much better energy management, especially in the off mode. The disadvantages are mainly the lack of accessories in the set, e.g. an Allen key to unscrew the housing and a ridiculously short USB cable - 10cm. Nevertheless, it is a very unique device and fills a large niche in PCBs with built-in instrumentation, i.e. display, sensors, loudspeaker, battery. And all this is closed in a neat, small housing.
