My wife loves her IlluMask (at least it makes her feel good if not younger), and the refill controller is easy to use. I hate the "refill controller" because it is not "refillable." I cannot find a way to replace the batteries and reset it to another 30 doses, the way I could on the older version of the controller. Has anyone out there found a way to refill it for the cost of 4 AA batteries?
