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

The product is so poorly documented that it cannot be used. 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 gone, who will have access to your code, and so on. This is a terrible product with no documentation. It can't even be returned since it's in the US. They charge shipping to China and charge restocking fees making this entire purchase a waste of time and money and not returned. I'll keep it in case tools or documentation are made, but I doubt it.
