There is no "risk free trial". My target device is an Amazon Fire. This is an Android device. After downloading the Android license (for which I was charged approx $59+), within 5 minutes of trying to install it I knew we had a problem. I got on line with their chat technician, who confirmed the software was not compatible. That person suggested I fill out a refund request. Which I did. At this point the purchase was 15 minutes old. One week and three nasty email responses later (from their "customer support team"), no refund. Nor will there ever be a refund. I suspect they make much more profit from people like me than they do from real customers. "You will be ripped off". That statement should be their written guarantee
