Review on 🚴 Szzijia 24V 500W Motor Brush Speed Controller: Powerful Upgrade for Electric Bikes, Bicycles & Scooters by Zachary Cha

Good product that gets the job done and has a lot of extra features with no info on how and where to use them. Only the block drawing and interfaces are on the side of the block and everything is in Chinese. Selling in the US market requires a good layout of all entries and exits and their placement in English. The seller must show the connection diagram and what and how to connect to it. They don't tell you the information you need to get it right the first time, but they do tell you not to make a mistake connecting it or you could damage your device. A savvy techie will be wary, but the user of the end product may not understand or smoke it well.
