Delivery takes a long time, comes indeed from Japan and the Customs takes a lot of time. Apart from the dimmer is good and does what it promises, I use it not only in the car but also in the house, but I disconnect the cable from the power supply terminal and the dimmer in between.
Did, for example, image tinkered with Led and steer the lighting using the remote control. On / off and dim with the handy use is very convenient, I can recommend every hobbyist.
