See the banana plugs at first glance does not look bad. All parts have another large tolerances. When using 1mm thick speaker cables, the cable was on a plug (three were OK) due to the tolerances (the clamping screw wobbles in the connector) not tighten. Only double cable thickness (bending the end) secure attachment was possible.
Conclusion: with manufacturing tolerances are too great. With thin cables provides only partial functionality. Only recommended for thicker cables. Look chic, but are not manufactured präzisse.
