As far as results are concerned, I’ve let a number of people try out my Magic devices. I had to buy an extra Mini to lend to people because it works so well. The Big Magic stays home. While I’ve had great results with short term demonstrations of the Mini, the Big Magic is a device you spend time with and frankly, I’m just not willing to be without it. I sleep with mine along my spine or with my shoulder on it and it’s great. I don’t have any seriously degenerative spinal issues. But I spend a lot of time on my feet, a fair amount of time climbing up and down ladders, etc. So at the end of some days, I’m needing help. Instead of popping a couple of Ibuprofen, I get the Big Magic on my lower back for the evening.
My wife uses it frequently and it helps her too when her lower back is driving her nuts.
