I use this as my standby EFIS. It's inexpensive, easy to install and configure and works pretty well. I had to use it as primary for an approach and landing last month in Indiana, it performed well, gave me a dependable airspeed when I needed it. I will usually run it in HSI mode, you can set it to simulate ADF and VOR based on the GPS. This can point to a navaid or an airport and will show the bearing and distance to both of them at once. Quite handy to fly a circle at a set distance from a waypoint or a DME arc. I have had a number of instances where it loses GPS signal, but that doesn't impact the PFD, just the HSI.
In short, I don't regret this purchase at all. I'd buy it again. I don't know how it compares to a Garmin G5 or a Dynon D10, but it has similar features and a much better price.
