The worst purchase for a plug that could be made. The construction, when you hold it, seems good and quality, but it is much worse. The safety has no reset at all, and in fact, one came broken and faulty. On the other hand, the screws for the wires held nothing and are only for thinner wires, and as it seems, they are made for lower performance in sound as they are also a copy of similar plugs from Neutrik that cost about 5-10€. It should be noted that I was very careful in use, and besides that, this particular plug damaged the sockets of 2 speakers, so it is better to spend even 5€ more for a GOOD plug
