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. 

Materials: Sarlink® TPV 4165 Thermoplastic Vulcanizate (End caps), steel with plastic dial (thermometer)

Weight: 0.4 lbs per pair

Warning: the thermometer has a sharp point covered by a protective rubber cap. Handle with care.

Care Instructions

Sanitize/Cleaning. We recommend cleaining your device in between uses by different people. The device (metal cylinder) and its color should hold up to any cleaner of your choice. We also recommend hand cleaning the rubber end caps, inside and out, with warm water and soap weekly.

Do not squeeze the bar too hard.You do not want to limit blood flow through your palm, you simply want to cool and and have it circulate back through your body

Do not get the bar too cold.If you use the AF Charge Bar when it's too cold you could trigger your blood vessels to constrict. This is because you're sending a signal to your nervous system that you are too cold and it will want to take measures to heat you up. 

If your AF Charge Bar is getting too warm, just take off the cap and fill it with water from a water fountain or sink. The cool water will bring your bar back to a cool temperature rapidly.
