I have a brick (core) with the V7 and the Oudie. The V7 is configured to give warnings as well as the Oudie. I do have a Butterfly display as well.

The V7 and Oudie will give adequate warning but as Matt said, a dedicated display gives better awareness of other non-threat aircraft.

The PowerFlarm works well as a logger and downloads only take a few seconds to a thumb drive.

I am still getting used to the system but like it better as I use it more.
