The Chinese Strobist blog has published a detailed review comparing the performance of the Canon ST-E2 Speedlite Transmitter and the new Yongnuo brand model (not yet released).

The testers extensively evaluated the design, controls, range, and performance of the Canon and Yongnuo units against each other. Results and conclusions are summarised and averaged in the table below. Most notably, the Yongnuo model offers a swivelling head, AA batteries and a longer range than the Canon.
