More effective than heating pad, terrible battery life
Used the pad a few times now and I can say this is way more effective than my old school heating pad at treating my SI joint RA  pain. And while I like the idea of the app, I question the security of Chinese developed apps with no reviews on Apple Store. Also the battery life is terrible. I only get about 1.5 thirty minute sessions on a full charge, it takes several hours for the pack to charge fully, and it doesn’t operate while plugged into AC power.
