Good charger, but is NOT a fast charger!
There are fast 1-hour chargers with a visually identical design. On fast chargers, the central open slot is claimed to be a feature that helps cool the batteries, which can get quite warm during a fast charge.
I thought I was getting a fast charger, but this is a conventional charger that takes 4-8 hours to charge most cells. Yes, this information was in the description, but I gave 4 stars because I wish it had been more easily seen. It feels like a bit of bait-and-switch going on here, between the photo and the description. Not fraud or lies, just misperceptions that easily could have been avoided.
This charger does provide 8 slots, which was my primary need.
It has the added benefit of not having an external power supply: Its cord plugs directly into the wall.
Still, it is a VERY good value, even as a slow charger.
