These devices are designed to take over control of the heli when you lose control. I personally feel that if you want to learn to fly, you need to learn everything from the beginning without artificial help. One piece of kit i was impressed with is the new Align system that no matter what you do to the heli, whether its inverted or what ever, the heli will correct itself and if you dial in a min altitude the heli will not allow it to drop below that height.
