Mine arrived yesterday also, and it works well. It's a little fidgety aligning the contact pins so they go into the proper slots. The directions say to plug the charger in first, but I think it better to get the battery hooked up first and then plug in into power. It looks like it will work better for batteries like the M8's, with slots, as opposed to ones with flat contacts (like the DLux3 and others) because the charger's contacts are flat blades. It would also have been nice if there was the capacity to charge 4 AAs instead of just two. I will continue to take the M8 charger along, but as a backup charger for several items I might travel with, this Ansmann is great!
