I have bought this product where I say the beginning must have the controller is not so Fubktioniert how I wanted it, was zumbeispiel problem that the connection is constantly interrupted or a key has not fubktioniert. But that team of CSL hat very good and competent care of my problem. Who apologized and sent me 2 new directly after one day was immediately with me. I am super happy jetz and can now no problem to continue the Controller Fubktiobieren properly. I would recommend this product only on and in case of problems not shy, the employees are very friendly and nice, super Sercive and thumbs up
