Everything seems to be hardwired, no integrated circuits. It's good. It has a beautiful aluminum body. It is passive and requires no power. The switch works fine. The clasps aren't the strongest, but everything clicks. I don't notice any crosstalk when switching to unused channels. I've only used two so far. It is nice and neat and looks like the original. Not like others with purple buttons. Nothing to do with the Switch, but it took me a week and two tries to get hold of it. The first was taken to an unknown location. According to tracking, it was delivered and handed in at the post office. That's great information, but I don't have a PO box at home. The second one eventually made it to my house but my neighbor had to stop the delivery as it was being dropped off at his home which is around the corner and on a different street from my address. This is not the first or even the second time. So much for Prime shipping. But I have to give credit to Revain, if you have a problem they will always solve it somehow.
