Anyone have experience on the quality and robustness of these flexible drive shaft tools (Silverline, Rolson, and unbranded):-

They are for use on dremel type tools. I have a B&D tool which is useful for fine work.

First and last are the same, Rolson same with different holder, all crap and useless. Had one ages ago couldnt do a thing with it, gave it away.
Not a fan of Dremmel stuff but i do have their robust one which will power a 3" dia 60 grit flap wheel from small lathe or smaller miller. Very little vibration and binding at up to 2000 rpm even though its rated at 30000 rpm mmm reckon wouldnt last long.

one of my toolmaker friends has an old dentists drill in his shop.He says it is the best flexible drive he has ever used and he got it for free from his dentists when they upgraded.He also collects all there old bits and resharpens them for his own use...lol
