Sanitize
Writes, deletes, and formatting all take their toll on memory cards. Innergize cleans and restores the flash memory performance of your OWC Atlas memory card so you can get the best results on every use.

When new cameras or firmware updates to existing cameras are introduced, they may not work properly with flash memory cards. Innergize gives OWC Atlas memory card users the ability to quickly upgrade their firmware in the field for full compatibility, additional performance enhancements, and bug fixes for optimal reliability.

Customer Reviews
The cards work very well in my new camera (Olympus) OM-SYSTEM, OM1 but the cost was excessive because on your website you say that the costs are paid and I had to pay 36€ for Fedex and then at customs I had to pay 63€ more because if I didn't pay it I couldn't pick up the cards and with all this they ended up being very expensive.
I would recommend this product to a friend!
