I spent hours comparing different red light devices and ultimately purchased the AllevaRed Pro Light Therapy Belt for myself (along with the compatible Powerbank). So far I am very happy with it. Instructions are easy to understand so I wasn't nervous to use it. So far I have found relief for my left knee which has been problematic for weeks and also my lower back - have not noticed nearly as much pain or flare up since incorporating this device in my routine.
I love this belt so much, I got it to help my stomach recover after having my baby, I bought it 3 months ago and didn't unbox it until a month in a half ago after I gave birth and when I went to put it on today none of the lights worked. I bought the battery pack and everything, I'm super bummed it's not working as I have not really used it but maybe 15 times.
I'll fully admit I was half expecting to be mad at this product or that it was a complete scam. Couldn't be more wrong. Took care of my tendinitis and I saw improvement very very quickly.
You should be able to refer to an order number or make it easier to access our account for a copy of the receipt. Perhaps I am not tech strong but you can make it easier to get your warranty. Why make it hard?
