My two cents
This is the second digital radio that I bought.
The reason for this purchase was my first radio (the AT D878UV+) actually. I wasn’t able to program it anymore and it din’t even announced itself on the USB port of my computers (neither on Windows, Linux or macOS). So when I sent back my first radio, I bought this with the hope, that the high priced radio would not let me down that easy ;-)
I like the radio very much, it is very well made and I like the fact that you just can type in any talkgroup and hit PTT to start the transmission.
The modulation is also very good and the feedback suppression is a good addition.
