Hey they came fast and the right model. I have used them and came to the following conclusion.
You get what you pay for. If you want to buy a batterie for $30 with the original manufacturers stamp on it you can, and if you want to spend the same amount on 4 batteries from a no name Brand, you can do that too. The difference was; Even so the no name brand is not holding the charge as long as the original batteries do, it still makes more sense to me to have rather 3 backups, which you should have at least one anyway.Maximal Power DB OLY LI-50B Replacement Battery for Olympus Digital Camera/Camcorder (Black)
