Poor quality
These banana plugs are not expensive, but they are of rather poor quality.
For a start, the drilled screw (which should hold the cable firmly in contact with the plug) has a sharp tip and the thread continues to the end, resulting in the wires being cut at the slightest tightening. Normally, there is a flattened or rounded tip to bend the strands around and wedge it neatly into a notch in the plug. In addition, the screw does not abut the plug, even when the coloured plastic washers are removed. As a result, assembly is neither easy nor very clean.
Secondly, there is nothing to block the cable at the level of the insulation (which considerably increases the risk of cutting the strands in use).
As for the plugs, they seem rather fragile... better avoid handling them too often.
In short, if you are looking for banana plugs for frequent use, don't bother. If it's for a one-off assembly... why not.
Concerning the delivery, be careful, it's loose in the box... for my part, I even miss a piece (one of the screws). Fortunately, the screw pitch is metric, so you can replace them with small standard bolts.
