■ The catch — co-equal billing, always
It is not a SNOO. It re-settled the baby by itself in about 44% of cry events — the other half of the time you are still getting up. It rocks more gently, carries no FDA authorization, and is rated only to 20 lb / ~5 months.

The six-month cliff
Every model here but one is infant-only: SNOO and 4moms stop at 25 lb, the Gracos, Starling and HALO at 20 lb / 3-5 months. Only the Cradlewise reaches 24 months. You are buying about half a year of use.
Translating isn't soothing
"Smart" covers two different products. The SNOO and Gracos *act* on a cry; the Maxi-Cosi Starling's CryAssist AI only *tells you why* baby is crying — and it has repriced to ~$950-$1,099, near-SNOO money for a bassinet you still work yourself.
Smart is not safe
No smart bassinet detects or prevents SIDS. Only the SNOO's claim is FDA-reviewed and it is a De Novo authorization for back-sleeping, not SIDS prevention — and it only holds with the proprietary SNOO Sack clipped in. AAP rules apply to all of them.
