For the price this is still a good product. Because for the same price you also find little bad plastic banana plug. This one is of good quality, well made, good contact of the banana plug. The only problem is keeping the cable: indeed the terminal screw is hollow; the advantage is that you add a little wire in the extension of the plug or on the side, but the downside is the point of contact between the wire and the plug remains thin, over the screw does not close completely and there is a space a little more than 1mm. Facheux when we HP cable 1,5mm²! it is very difficult to hold. So beware. My advice: strip the longest son to double in detail; it works well. It remains a practical product for one who has a HC amp 5.1 - 9.1 and that will not be ruined.
