The sorting of lengths makes sense. Of the short bridges which are most commonly needed contains the bundle also most cable. Less colors, so that more of the same bridge of the same length are present would prefer me. But that does not detract from the function. From a certain number of these flexi jumpers the circuits are anyway too opaque.
As already mentioned several times by other shoppers, enter the cable from a chemical smell. Abgsehen the smell a strong buy recommendation.
