I love Lifepro red therapy products- I have the belt, neck device, lamp and sauna. I needed something small to travel with and to use on our dogs. This is perfect size. Using i regularly has helped my back, neck and knee pain. I got this little one to use our old dogs to see if it will help with their pains. They can't talk but I want to believe it is helping them.
I’ve only had this for a short time. Noticeable difference to skin already (stomach stretch marks). I can’t speak to long term use for pain/skin. Prompted for review while registering warranty.
