The first observation was that they were very very light and I couldn't use them at all to adjust trim as I can jetfins. Second observation was that my standard modified-frogkick which gets me along nicely with jetfins did absolutely nothing with force fins - they appear to need a completely different finning technique which didn't match mine at all. Third observation was that moving my feet I couldn't really feel the fins, and using them to balance in the water didn't work for me at all.
That's exactly what I found. No "feedback" as it were, you'd no real feeling of any response from your feet. I found that a bit off-putting.
