TALK WORKS Nintendo Switch Joy-Con 4-Remote Charger Dock

I have had this docking station for a little while now and like it quite a bit. Though I am up in the air about a few features it doesn't take away from the fact it does charge the controllers. - When the controllers are docked it will only charge 2 controllers available time when I view them from the controller section of the switch. (when you un-dock one controller and dock another controller it will charge the two most recent controllers that have been docked until completely charged before it charges the others) - the lights seem to be timed than actually turning green when it is actually charged. (When I take them off and put a fully charged controller on it will be red again.) -regardless of that it does charge all of the controllers. All in all despite the fact that it "APPEARS" to only charge two at a time and the lights seem to be timed, I bought one for my niece for her birthday. For the price and what I want it to do, it has served its purpose and held up very well, and my family has used it every night.
