I have a Felo Ergonic 1/4" drive spinner handle. Handle material has held up fine. I use it for small 1/4" sockets instead of having a bunch of nutdrivers. I prefer the Wera handle, but there is nothing wrong at all with the Felo Ergonic.
I've used Felo #2 bits a lot (those are the free ones KC Tool sends with orders). They seem to be good quality and hold up pretty well.
