Review on 📱 Seeed Studio ESP32 Development Board with 3.5in Multi-Touch LCD Screen - Bluetooth/WiFi, GUI Firmware, Dual-core MCU - Buy Now! by Kyle Merriman

The product is so poorly documented that you can't do anything with it. The Arduino support is buggy so you have to use the web app (login + password) to write your code, who knows when the web app will be removed, who has access to your code and so on. This is a terrible product with no documentation. Can't even return it as it's based in the US, they charge for shipping back to China and charge restocking fees throughout the purchase. Waste of time and money, don't go back. I'll keep it in case tools or documentation are made, but I doubt it.
