works well
works well , leds are red when charging & do turn green when batteries are fully CHARGED.NOTE when changing charged batteries for uncharged I found it necessary to unplug the power & reconnect to reset the leads from green to red.

Charge indicator!
The charge light remains red so there is no way to establish whether fully charged or not!

18650 charger
It's OK reasonable value for money but as it is usb charging it does take ages for a full charge.
