Yep. Read about them and when Cosco got them a few years ago bought a couple of packs. Compared to all the rest of the rechargible batteries I've bought and used, these don't loose a charge in weeks, work well and don't have to be culled for bad cells.
They work as well as alkaline batteries for my flashes and other devices in my experience.
My old NiMH batteries would need constant chariots after a week, cells would need constant checking and were always a PIA.
I've gotten rid of most of these old batteries and upgraded to the Eneloop and I need many less. Well worth the additional cost difference IMO.
