I got this when I started having trouble charging my Arlo Pro 2 batteries by connecting the cameras to chargers, that were turned on when you made a purchase. I have 4 cameras and could only charge 3 batteries out of 5 so I ordered a 6th battery so I can use all my cameras. Then I put bad batteries on this charger and discharged it, and lo and behold, I started charging right away. Within an hour or so it was fully charged. The other didn't seem to charge and I moved it between trays several times. However, I left it charged overnight and when I woke up it was fully charged. I assume this charger restored it? I definitely like how it lets you tell when the batteries are charging and how charged they are. I now have 2 extra batteries that are fully charged. So if they start to run out in the cameras I can now "hot-swap" them and have the camera up and running again in under a minute instead of having to take it out of service which annoyingly took hours to get to had to connect at night. Considering the batteries are $45 each and I've had 2 misses, this is totally worth the $20-25 I paid (I don't remember) as it saves buying additional, unnecessary ones Saves on spare batteries and makes it easier to maintain cameras.
