I have met the man and seen the blades in action and they are quiet. Power production seemed similar. However, the first set was rejected by the buyer due to a serious defect (I think one blade was longer). After the buyer installed the second set, the seller asked for (EU50) more money than was agreed. I was there and first hand saw & heard all this. This was at Grenada and the man said he was the inventor and had several sets aboard his boat to sell. The money dealings were VERY strange. I would only buy these through a trusted US dealer with return for exchange/refund if defective.
