These are the four 'must have's" for any user who flies into the Alaskan wilderness, and are worth every penny at retail, but are absolutely fantastic at these prices. I purchased them when they first came out, and have had a blast. Thranda makes great software, no doubt.
The only thing that I can see that needs improving. I have a 4k monitor, and it's hard to make changes to the slide-out Panel Layout screen
-especially the 'Panel Preset 0' selector.
The lines are so close together and so small you almost need a magnifying glass to choose another panel number. (and the selector is 'disguised' as part of the displayed line)
But this is just a minor inconvenience. Overall 5 Stars, for sure.
