This is very good value for what you get. A complete ESP-32 board with Oled display and LoRa WiFi, tested and ready for development. I just did a quick thumbnail rendering demo using the U8x8 library in this video. I have to say that the only detail that doesn't suit me is the battery charge, which in my case isn't the best, so we have to point that out to the Chinese manufacturer Heltec.
