Who should buy it (and who should skip it)
This dimmer is for DIYers, hobbyists and anyone using LED strips behind a TV, under a cabinet or in an aquarium hood who wants brightness control without rewiring. If your lights run on a different voltage, use a connector that is not a 5.5mm barrel jack, or draw more than 3A, look for a different controller.
