GOOD, It works, but I connected another connector, the cable colors are incorrectly connected, it should be blue negative, brown +, but your cable is Blue +, brown Negativ, If the customer does not cut the cable and measure, the device will explode. I bought it from you for the second time, 1. I had an explosion when I bought it once 1 year ago, nothing happened to the device but this is a bug.
Product as described Only canonhead connector is not from metal as shown on picture but plastic.
