Today, too many alternatives exist, with at least the same or even better performance, which you can buy less than a year of this subscription. Sorry, but these receivers are extremely overpriced. I work these days with an r12i and a CNC nav i73, and I see no difference.
Guess you haven’t been keeping up with what’s happening in the world with PRC products. I could show you a document from the federal government about using those types of receivers. Good receivers just where they are made.
