The small little device trained alongside the fingers and the palm of your hand and the whole forearm, depending on how you use it. All 4 fingers can be adjusted continuously in force on small actuator wheel under the mechanisms. That's a good thing, because hardly anyone in all four fingers has the same force. So you can for example. Specifically train the little finger when you here has shortcomings.
But after some time, the part begins mightily to squeak. I have to because even with oil ran, so that gives back. Can more relaxing when you have passengers in the car.
One important thing is to be mentioned: Who sees this as the Holy Grail, to order the part and losdrückt uninhibited, should keep in mind that you are also promising us certainly can provoke tendonitis ignition. So rather make only times going on when the muscle is not yet accustomed to such a thing.
With me was, even though I have some real than 2 hours a day in the car rumgedrückt it, nothing. I play for example. For years electric bass fingerstyle much stuff beyond 230 BPM. Maybe it's because my tendons that do not mind.
Regardless, with the exception of Quietscherei that is certainly easy to fix that part is great. Buy it yourself!
