They are very good!
I have worn them a few times already, 2 or 3 times. But it is hard to not take them out in certain situations, it costs a lot of discipline to go through and just let them in.
the look of the relatively thick wires is not so bad, people do not stare. But i really feel uncomfortable talking. the plates are not even so thick but still give be a lisp. And if i talk, people try to find out why i have this lisp i belive...
