I've not tried the brand name versions, but these work really well and the zip system seems reliable. Can't find a sensible use for the mesh/transparent reflector though, other than to block unwanted light without adding unwanted colours.
Great batteries, great price. As good as the Eneloops when used in our cameras. They've been in my wifes bridge camera and taken over 1/2 GB photos with flash and still had life left for more. The previous, (much higher capacity) standard NiMH batteries we have used would have given up the ghost well before then. Storage case is useful to keep charged and uncharged sets separate, and helps keep them together in your bag or pocket.
