Heating area is only 12"x19". The rest is a border that doesn't have any heating properties.
While this heating pad is touted as being 28” x 17.3”, that measurement is only for the entire unit. The heating area where the stones are is only 12"x19". This is also the only area of the pad that has any heating properties. This makes it rather bulky for providing such a small actual heated area.<br /><br />The User Guide and Instruction Manual that comes with the pad states, "This Far Infrared Heating Pad works a little differently than your standard coiled heating pad. Please allow 5 to 10 minutes for the far infrared energy in the stones to build up and for the pad to heat up."<br /><br />Well, I've had my pad plugged in and heating for over 25 minutes & it still hasn't reached the 150° temp I set it for. My house's temp is 62° & so far the best my new heating pad's controller has been able to read is 140°.<br /><br />Perhaps these tourmaline & jade stones will radiate the heat more deeply into tissues, but so far I'm not convinced that this pad will be useful for any areas smaller than those mentioned in the description - back, neck & shoulder. It seems to me that attempting to use this pad in anyway other than flat out won't be easy.
