*by F***X on 11 October 2024*

Charger does what it's supposed to, keeps all my batteries charged independently, few things we have noticed using the charger is it does have a quirk where depending on which slots you put the batteries in some slots seem to be tied together lighting 2 slots rather then one independent slot as it's designed to not sure if this is my unit being defective or if it does this with all of them. Also if the rechargeable batteries are close to the end of service life the charger errors out or will give up trying to charge those specific batteries, however it's to be expected just throw the batteries out if they get to that point. In all , this charger is perfect and gets the job done. I would buy again and suggest it to anyone who needs a great multi slot charger.
