The jumpers offered here are significantly better than that though more favorable, but difficult to be used with the round connectors. During the round plug does not fit side by side in socket strips, can the jumpers offered here wonderfully juxtaposed use, since they correspond to the form factor of the male connectors.
Unlike the jumpers in wire version (which in the transparent plastic boxes), these will also use much more flexible and do the work on large breadboards easy. However useful is a combination of both types. So I use the jumpers for the power strips and very short connections, everything else is done with the jumpers or the same in the 30cm version offered here.
Conclusion:
The initial smell dissipates fairly quickly when the jumpers all separated and can lie to two days in the fresh air. After that you are largely odorless.
At this price, jumpers themselves to manufacture hardly, even apart from the weird time required for assembly. Therefore, I recommend to anyone who frequently more complex or larger circuits on a breadboard builds the combination of these jumpers in different lengths with simple jumpers.
