I like the little tail on them. A fish hardly a foot long would have a larger tail yet these "tails" are supposed to aid the propulsion of a scuba diver. They would need to be about 3 feet across to be in scale with the human fish. It is just more of the ridiculous BS that gets pumped through retail dive equipment stores and much of it is in common use as required gear.
I don't think they are all that similar to a FF. The FF has a design rational and a bit of engineering and they are a functional fin for many divers. To compare them to a FF is almost an insult to FF.
