charge controller as described. However, the description also states that the red light is charging and the green light means fully charged. My block doesn't have that. One light is ALWAYS red and the other ALWAYS green, no matter if I put a fully charged controller on the left or right charging dock, so you can't tell if it's fully charged or charging. It also requires little effort to connect. controller into the docking station and requires two hands to remove. You must hold the base while removing the controller or it will not detach and 2 hands to place it properly. Small inconveniences but annoying.
