I bought a set for research reasons and have enjoyed fiddling around with them.
I have not played with them on the table yet but I find they are easier to turn and look pretty nice.
swapping dials for ships is pretty easy just press on the ship icon and the rim and they pop apart. not sure i want to add yet another thing to assemble and find before i get to play (already you have to assemble basses, cards, id tokens, BUGH!)
not sure how many i will get. i do wish there had been four dials in each kit as this would give me enough dials for 90% of my lists. as it is three is not enough and 6 is too many for my playstyle.
