Excellent quality as you'd expect, easy to solder, and will take a decent diameter of cable, however they are very robust and give a very good tight grip on the socket. The only problem is when plugging into some domestic equipment it nearly pulls the socket out of the equipment when removing. Overall very good, but if you need something to patch in DJ's etc and are therefore plugging and unplugging on a regular basis maybe get something cheaper, if you want to patch something in semi-permanently, these are the things for you.
