I bought this from Lazada (purchased 29th july) link
arrived last saturday.
tried it on backpack , not with osmo pocket but with dji osmo action (with rock steady feature on)

same like the video u shared.
looks abit weird (jerky) bcoz of walking motion (up and down motion).
and unless u walk like robot, u will see footage go kiri kanan kiri kanan too when u take each step.
not suitable for walking motion, best on bike, bicycle, skateboard etc.
walking better with head strap or chest strap

[edit]
i bought 2 alternative to this before.
a cheaper one by Telesin, link.
arrived within 2days or order
clamp to bag quite tight, but not as secure

Telesein brand as well but with gopro quick release mount
i bought this one first. quick delivery too.
wore this with bag on bike, very firm and secure.
