Im a UX researcher and Ive been using this app for about a week now, it works exactly as it says it does, the videos are good quality and include useful gesture recording including tap, swipe, scroll, and pinch & zoom. I have a second video recording backup system, but nothing has gone wrong with the app yet in terms of reliably getting video. It also gets video of the participants face without a big intimidating webcam sled setup. Sure it has its own browser but it works with InVision prototypes just fine. And sure it costs a lot, but the unlimited has already paid for itself many times over in terms of usefulness AND ease of use / good UX in the app itself. I think this is the first time Ive ever paid for an app, and it was actually worth it so Im extra glad.
