This stick seems to have captured one or 2 peoples eye and whilst they attempt to tell us all it's technical wonders the truth about this stick is that it is cheap...
The rudder control situated on the throttle is nothing new and I first saw this configuration on a Saitek X45 HOTAS.
At best it works okay but the problem this has compared to a twist or pedals is that it forces you to use a couple of digits (fingers) on your left hand to control it. On my twister those same digits will be controlling a hat switch a roller switch and a button or 2. In other words the this configuration reduces your effectiveness

I have used this stick as a friend of mine bought one recently. It works ok but I wouldn't encourage anyone to buy this stick it's just not good enough unfortunately. My friend I am glad to say is sitting with an X52 pro hooked up to his PC now, he smiles a lot nowadays.
If you wanna buy cheap kit by all means do so...
Please don't try and sell the idea to other folk your cheap kit is wonderful...
