The plate after level 30 does not increase in intensity. Not sure if this is a manufacture or design issue. We bought the more expensive version to get the best results but can't recommend at this time.
Love how this has already changed my mind I’d, sleep and back pain. I’m sleeping better and have noticed less back pain throughout my day. I use the Rumblex along with my Lfepro Red Red light vibration belt. ⭐️⭐️⭐️⭐️
