Ground and ring connections faulty, with lots of adjustment you can make it work but I doubt it'll last without constant adjustment. Save your money and time and go for the real thing. Tested 2 of the 4 I bought and both have the same problem, returning all of them.
I was initially very pleased with the appearance and look of quality, but unfortunately the quality was only akin deep. I had to adjust the contacts in several of the units, and after 2 uses one of them has failed. I am now concerned about the other 10 that I have on stage. Save your self the time and headache of replacing them by buying a better product.
PROS: They are cheap and look nice. Some of them work great.
CONS: Contacts are very weak, locks are very loose
