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.
Since using this product, I have noticed a significant decrease in my shoulder pain. It has been a more effective solution than weekly massages, as the pain no longer returns the next day. I am grateful for this product and its ability to alleviate my discomfort.
