IF all the online stuff is true:
The amazon one is outa stock
The first one from banghard or banggood or whatever claims that it is soft until it sees a hard impact - like the non-Newtonian fluid gels etc they use in shock absorbers etc ---- so IF that is the case its far superior and might be woth a lot more
BUT really - FFS $200 for a hat that a $20 helmet will do? Sounds like everything we see only priced in euro's

So what we neeeed is somebody to scan the amazon one and give us all a file to get the thingy cut from EVA at the local laser / waterjet cutting place...... cos its just precision yoga mat.
