It may have been me, I had a hope rotor that was rocking at the floating join. Couldn't get it sorted so just replaced with another hope (only one I've had an issue with in that regard anyway).
I've got a few sets of Clarks floating rotors I've never used, they look and feel as well made as other known brands, not sure how they compare to the ones posted.
I've bought some of the 1x chain rings from the same brand (there seem to be a few that all look the same but different brands) and they've been good, not made of cheese and do their intended job. I'd assume similar of rotors.
Floating rotors look cool, but if you are concerned just get normal ones. That said, looking cool counts for a lot, just depends on how you intend to use the bike, finding out the hard way they aren't any good won't be fun, but they must sell thousands at that price so any issues with them you'd expect to be able to find online.
