I bought a GoPro last year after reading about a feature HyperSmooth Pro stabilization. Granted, I didn't do an inquisition into the specifics just thinking if I bought their best camera it was supported. Feature is only available if I also subscribe to their $100 per year membership. I think without the membership some lesser, non-Pro version is available. It felt like a bait and switch situation to me when I unboxed it and tried to use the feature the first time.
