The Programm is really cool! When tricking around a little bit with the various presets (literal hundrets) you can get a really really really enjoyable end product. What I have to say, is that the interface of the app is really unenjoyable. Ypu always get thrown back, don't remember what you selected after puting it onto the game to try it. So that is really tricky. However, installation on the other hand is SUPER EASY. You literally download it, run the installer, and DONE. You can even have your game running while doing that. I did a long flight, bought it on my way and used it already for landing. I am very happy with it after the first few days. A friend also immediatly bought it after he saw I was happy as he considered already for quite some itme, and he is happy aswell.

This product doesn't work; you should all be thrown in jail for selling this garbage.

1 star until an update comes out with SU4. Completely unusable as it crashes at every start.

The add-on is very good, but the interface is awful. For example, you can't preload a profile that remains; you have to manually reload it for the three categories each time you use it, and the way you create and load them is very poorly designed, even though REX has traditionally offered better interfaces in the past. Also, since Sim Update 4, I can no longer use it because it constantly closes after a few seconds.

“Waiting for Simulator” when MSFS is already running, so it will not detect it. Also, the application opens then crashes if you open it during an MSFS session. Asking for a refund.

I have to say it's good but only 3 stars because the interfaces aren't really user friendly. Specifically, you have to barely advance each parameter to make adjustments. I mean, just nudge it. Advancing each far left or far right yields unusable results. It would see the folks at REX would understand we're all hobbyists and they are the experts. Please make an interface that is more user friendly to experiment with many different results. I've used many REX products throughout the years, and experimenting with this one is a bit of a hassle. And after all of that work, the results won't leave you blown away like other REX products. The main saving grace is that it is affordable.
