Got to play with the Osmo Pocket a bit, I would say that the small size form factor is where the value is, with regards to comparing to older DJI Gimbals, I would say it is not as expected, does not meet my expectation.
Nonetheless, I would still use this over my other DJI Gimbal due to the small form factor alone, but if you want better footage, use the GoPro+Mount accessory with DJI Osmo Mobile or Mobile+. This GoPro Osmo Mobile combo creates better footage plus I can use Filmic Pro whereas on Osmo Pocket Mimo is the only option, Filmic Pro not supported (well hopefully soon?)
