Review on ACTOO 4 Pin RGB Splitter Extension Cable: Connect & Control 2 LED Strip Lights with 1 Connector – Perfect for 5050 3528 2835 RGB LED Strips (2 PCS) by Pete Juarez

Works great for splitting 2 RGB devices into one RGB connector on my motherboard. The adapter even comes with small adapters to connect male or female ends. If you want them to be a tighter fit, put on heat shrink tubing and then heat it with a hair dryer, heat gun, or heat source to shrink it and get a super strong bond that will never come loose. Let's say they come in handy when you want your setup to look cleaner and only connect to a single RGB cable.
