Really liked the Mito light which reduced my inflammation in my ankles in just one day! Tried it the first morning under my computer desk and went to bed inflammation free for the first time in years. Like the options of having red and near infrared or both. Have also used it on my back with good results. Am reccommending this therapy to others with problems too. Turns out an acquaitance of mine, who does horse and dog therapy, has been using red light therapy on horses for some time! A travel sized version would be nice to have for when going on trips. Also, wish there was distribution in Canada as the customs and delivery were about 100 dollars.
