I like the ease of use, the ability to program things you want to happen. I dislike the lack of a programmable GUI for some things (like the web browser), but I know that will eventually come. I'd like to see a better GUI for some of the things. I'm able to program the PTT buttons for the mobile radio to press on the Zetta, which is great. I can also program the PTT button for my radio to press on the Zetta. It would be great to be able to have one button that presses both radios. My radio is a Motorola radio, so I've been able to program it to do many things. I've been able to program the Zetta to do many things also. I like that it is very easy to use and customize for our needs. It allows us to keep track of where our employees are at all times and gives us the ability to send them emails or text messages if they have not responded to a call within a certain amount of time. There isn't anything i dislike about this product. We are able to see who is working and when they will be available to work next.
