As someone who's dealt with lower back issues for 20 years (fractured vertebrae + 2 herniated discs which led to a fairly major surgery to repair the fracture), I get frustrated by products that generically talk about "back pain" as if there's only 1 cause and 1 solution that works for that cause. The reality is that there are many causes of back issues, each needing a different type of treatment. Make sure you understand (as best is possible) the cause of your back issues, and what sorts of treatments are safe/effective, before trying a product like this.
Wow... How do these things fund so quickly. Plexus could easily make this without funding and sell it but they are able to get people to pay for it instead... What a time to be alive.
