I have been trying to find a red light therapy device that is convenient and can be easily used while I work, rest or play. The other devices I have tried, have been large and flat, difficult to aim and somewhat of a hassle to use. For instance, I would like relief on my neck, but its hard to aim a huge square or rectangular product downward on my neck without mounting it on a wall. This handheld device solves some of those problems, it is small and portable enough to aim onto the affected surface. It is not however, perfect. It is easy to hold the product and aim it onto my neck, but after some time (prior to the recommended 20 minutes), my arm tires. On a positive note, it can be propped more easily than the others I have tried. For instance, when treating my Achilles, I can prop the unit in my other shoe (even when wearing shows). I can also raise my feet up and lay the wand down on an area beside the wound/injury to be treated. It is definitely a step in the right direction and my plantar fasciitis seems to have responded. Regardless, the benefits of red light therapy are becoming better established as we do more research on the subject. Overall, I like the treatment, but feel it is a little expensive. And more needs to be done to encourage these products to be fixed in place and leaned or propped and malleable. I will not deduct a star for the price because it is a therapeutic device, and its hard to put a price on health.
