I bought a Nikon MH-25 via Amazon several weeks ago, mid-July I think. I've had no issues with it. Works fine. I will say that there is some resistance when trying to mount the battery in the charger. It's a bit of a tight fit. However, it does go in and the battery contacts mate properly with the charger and then charges the battery. For the time being I'll use it as it's the only external charger with a battery cradle that I have. I don't want to keep opening the flimsy rubber door on the Z 6III and have the seal wear So I am in the market for a multiple cradle battery charger with a USB-C connection.
What did the sticker on the back of the battery charger over the word Nikon say?
