One review was not favorable:
Note that these "enhancements" are not the security patches offered by new releases of the Android OS. Those are delivered via OTA (Over The Air) updates.
For enterprise devices, these "enhancements" seem like they may be valuable. But do they offer anything for consumers who do not install software from unknown sources?
