So I was sent the pack of two sweat patches by Gatorade and Influenster. I decided to do some intense workouts at for an hour and half for one patch and one hour for the second . And whatever I did I could not fill this patch up . My face , neck back were soaked but the patch would fall off and not fill at all . The second patch spilled orange on my skin but did not fill up the lines and the app was terrible . I could not scan my sweat data , the app asks so much questions . I would not recommend this product to anyone , as I feel like actual athletes would have even more issues with keeping the patch on their arm . It’s not very sticky and falls off easy .
