First off, there's the chirp. You can't turn off the chirp. When you push the talk button, you have to wait for the chirp, then you can talk. If you're on the receiving end, you hear a chirp, then you hear the person talk. Looking around on various forums, this is the major complaint - that there is no way to disable the chirp.
The user interface is stuck somewhere back in the 90s. You need to separately purchase a proprietary keyboard to enter some of the basic info in, even though it seems like it would be pretty trivial to be able to enter that info given the available keys. For example, you can call a specific unit, but unless you have the keyboard, you can't change the name of the unit to something you can remember, like the person's name. Instead, it's just a long number. Clunky.
The power connector is proprietary as well. Probably also designed back in the 90s. Good luck finding an adaptor to charge this in your car. Maybe Motorola hasn't learned about USB?
If you want to use a headset with these, you need to custom program them. On a PC only, running a version of windows 7 or earlier. No windows 8 or 8.1, no Mac (good luck finding a PC in a video production environment). Also, it's a serial cable, you know, like from the 1980's. So you need a serial to usb adapter as well. So after spending $80 just to get the things to work well, and having gone to a computer museum to find a computer old enough to program them, you may or may not be able to use. I don't know, I gave up when I heard PC only.
The voice is clear, but there is about a 1 second delay. Side effects include extreme frustration, cursing motorola, and questioning God's existence.
