Bought for medical reasons to assist with personal research on plaque and calcification. I believe the cuff may be helping but it stopped working. The company has assured me a new unit will be sent. Although, it was a struggle for me to send the images requested of the failed unit, customer service promptly responded (giving them a four star review). I believe the face mask is helping and need more time using the mask to see/experience results. I am curious about the test results of the infrared using my smart phone.
