Build quality is good. Many digital features typically cost $300 or more. Programming is typical for these radios and may take some time to learn. It would be nice to have USB-C charging support like the HD1, but for the price, I'm happy with the included charging stand.
I just received my RT3S in the mail this week. I also had the programming cable and speaker mike included. I must be honest, that I was a bit nervous ordering this directly from the Retevis store in China and skeptical about the price. I couldn’t be more pleased with how everything turned out, especially the price. It’s one of the best dollar for dollar values for everything Included. The radio works great. I’ve installed the OpenGD77 Firmware and am thrilled with the radios performance. Thank you Retevis and I know I’ll be a return customer.
