Great for learning embedded systems
Works perfectly with STC-ISP software. The pinout is clearly labeled which helped me a lot during my project.

Good value but docs could be better
Hardware is solid for the price. I wish there was more English documentation available for the specific registers.

Excellent price performance ratio
Hard to beat this price for a 128KB flash microcontroller board. Voltage tolerance is as advertised.
