Red Light Therapy by VitaliZEN, 1000 Watt 660nm Deep Red & 850nm Near-Infrared LED Light Therapy, 200 LEDs, Low EMF, High Irradiance, Anti-Aging, Pain Relief, Energy and Performance

This was my first red light machine and I just went for the most powerful machine I could afford at the time, and boy I wasn't wrong in that department. It takes a little getting used to as it is very strong but that's what you want. It's heavy for the size, Oh, a little tib bit here. It is not as big as the picture has a person believe. It is much narrower than what I thought it was going to be because I went by the picture on the description page. Our whole household uses it. So all in all it's a good quality device. Also, the warranty is the longest of any machine I found on the market.
