I have this Led Driver now installed 10 times in my house and am very satisfied. The installation dimensions are very small. I could easily stow it in my hole opening of the recessed ceiling lamp. The transformers do not hum and verusachen no interference on the FM radio reception. I can not say anything yet about durability. Everything is going so far no problem. I operate the transformer with a load of max 16W. Delivery time was about 1 week since they are sent from England. Recommendable All in all, definitely a lot.
