Like every smart device, the Snoo isn't actually that smart. We have a 1 month old and bought a Snoo second-hand in anticipation and way before they changed the terms of their app.

Where you'd expect the Snoo to dutifully monitor the baby and gently increase the intensity of the motion to soothe the baby, it rapidly goes from a baseline to the highest level of motion and sound within a minute or so, which is both annoying for the parents and stressful for the child.

The motion locking feature was how we got around that poor excuse for engineering, but now that pretty basic feature is now behind the paywall. We just use it as a standard bassinet.

I haven't signed up for the added features yet, our kid is a pretty good sleeper at this point, but those features are a necessity to operate the Snoo properly, so I'll end up paying the premium (begrudgingly). As a parent I know companies are doing everything they can to get my business, so I'm not surprised by this behavior, but it's just a disappointment and annoyance.
