Works really good. I’ve bought many other red light products in the past and none worked as good. A little on the large side hard to wrap around arms and legs without overlapping.
It seems too soon to tell if the NIR light is helping to heal my foot. I use the belt twice daily for 20 minutes each time and have only been using it for one week. The heat does feel soothing and the belt is very easy to use. There are several family member's that can't wait for their turn to use the belt on their problem areas!
I haven't been able to use the quad belt because I find the descriptive info inadequate. First there's a list of all the included parts and pictures but their are no names near the pictures so I don't know what part is what. Then you say about the power bank "This option will allow you to power the light therapy belt with the external battery". So what's the other option? Then there's the warning "do not plug the wall adapter into the part on the left of the battery to charge it, doing so may damage the battery pack." Don't know what the wall adapter is.Next for mode you can select NIR. IS this a word I should recognize? For time select timer mode. Where is timer mode. And so it goes. At least you could have youtube videos showing how to set this up
