Review on L-faster 36V/48V 800W Electric Motor Controller: Optimal Brush DC Motor Speed Control ideal for Electric Tricycle, Scooter, and Brushed Controller by Rodney Mendoza

Arrived just over a week. No instructions, no English. The indicator light shows the battery voltage, in my case 36V, so it's useless for the indicator light, but plan on using it for the battery gauge instead. Otherwise everything works. It seems like a great value. I deducted a few stars, although due to the lack of information not 5V but 36V of the display circuit and the lack of English. Use it for a kids karting project we are doing together. It looks like it should work, and even if it breaks quickly, it's cheap, so I'm fine with that.
