The device does what it should ... and very good! Dimming and On and off by remote control. For those who need the Dimensions: 75x55x35mm (WxDxH) The device has 4 loops for screwing. very good! Labeling the ports is also OK and everyone should join his Led`s can. The flicker, I've also noticed, but only in the lowest level, which no one needs because they virtually "off". From then `s no flicker! The price is great! Delivery very fast! Overall "very commendable" and "highly recommended"!
