Bergey also has issues with those blades causing noise and vibration but feel that the low cost makes them perform/sell well.
Whisper used to use two blades but most of those machines shook them selves appart and went flying off their towers.
Simple Wind Turbine Blades is a rather good blade design, these machines tend to work and hold up pretty well.
