The AF Charge Bar (patent pending) now comes with the new TempExact Caps (patent pending). These end caps have a built-in thermometer so that you can tell exactly what temperature your device is at while you use it. For customers who purchased the prior version of the AF Charge Bar, the new caps can be purchased on their own and they will fit and replace your old style caps.
These caps have an improved fit and roll smoothly in case you want to roll your feet or some other body part over the device.
How the cap works: The AF Charge Bar should always be used with water inside. The thermometer of the TempExact Cap dips into the water of the device which dictates the temperature of the device. The ideal temperature for palmar cooling is 45-60 degrees Fahrenheit.
