I have chronic neck, spine and shoulder pain due to a wildly asymmetric body, so I'm up for trying just about anything.
Got it yesterday, and the first time I sat in the chair and put it behind my back, I heard 4-5 vertebrae easily crack back into place.
So I sat in my recliner and kept it there as some sort of stationary neck support. After about 20-30 minutes I replaced it with something softer, but:
For my singular purposes, this thing seems to have panned out for me.
YMMV wildly, and, yes, I'll bet you can pick this up on Alibaba for ~ $3 while waiting months for it to arrive, if ever. I've been known to needlessly complicate my life over pennies before, too. Hey, I'm an SD'er.
I get the anger/suspicions at SD and all, but me? I'm just waiting for some hyperventilating twerp to try and brand me a shill.

Here 'ya go, Leroy. [spineuniverse.com]
From the link, should it not go through:
"During a back adjustment, your back undergoes quick, gentle stretching of the spinal facet joint, so you may hear a cracking or popping noise. This is caused by small pockets of air or bubbles, which are in the fluid that surrounds your joints. When joint tissues are stretched during a chiropractic adjustment, the pockets of air "pop," which creates that cracking sound you hear."
From another link:
"What is that popping sound?
Your spinal joints contain "grease" known as synovial fluid. This grease contains dissolved gases. When your spine is adjusted, the spinal joints are gapped or opened, creating a vacuum within the joint. This vacuum pulls the gases out of the grease, turning the grease to foam. This release of gas is what creates the audible "pop". If there is no "popping" sound, it does not mean the adjustment was not successful, it simply means that there was no sound from the escaping gas.
That sound is not your spine "cracking" or "popping" like most people think. That sound is created by gas (in this case, nitrogen) rushing in to fill the partial vacuum created when the joints are slightly separated. Another example of this phenomenon would be the "pop" sound you hear when the cork is taken out of a champagne bottle.
Next time, perhaps educate yourself before you respond.
