I have been purchasing controllers from Led Strip Studio for the past two years and I have found them to be very reliable, easy to install and program, and versatile in their use in a variety of conditions. The interaction with Led Strip Studio’s staff during the purchase of equipment or following a request for technical support has always been efficient, informative, and courteous. My choice to use Led Strip Studio as my exclusive provider of controllers during the past few months reflects my high satisfaction in their services and products.
