I legitimately don’t know what else to say here. This little droid will wash / clean and DRY your coil heads. After the cycle is over you can use your freshly cleaned coil head immediately. This isn’t going to save a truly awful dirty coil head, It’s not a miracle worker. But it will certainly “refresh” it and will prolong the life of a mildly dirty coil head.

The RDA deck and coils I put in here came out surprisingly clean as well. Like I said in the video, it’s not an ultrasonic cleaner, but does legitimately work as advertised.
