I haven't flown much with it since the install (which is very recent) due to other unrelated issues, but first impressions are very favourable.
I love the near total flexibility of the screen layouts, which takes some time to learn but once you get the hang of it you can do some pretty cool things via your PC and a micro SD card. Nav and firmware updates are super easy too.
If you need more connectivity you can connect their "extender module" which gives you a bunch of extra serial ports, etc. However for my VFR 2 seater, it has everything I need and the Explorer (8.5") screen just fits perfectly in my panel!
