I really enjoyed using the Sweat Patch! It was easy to apply and use and the app was simple to navigate. I enjoyed getting the feedback from the app after my workouts. It provided biometric information I’d never had before. The adhesive didn’t cause any irritation though the arm placement of the patch was a little distracting, especially during weightlifting workouts. The only downside I found was that it took a solid 30 min doing moderate level cardio before I would get a reading, but maybe I just don’t sweat that much. I’d definitely use them regularly if they weren’t so cost prohibitive.
