This is a Snoo "smart" bassinet in clean, working condition. It worked great us (though every child is different). The only issue with the device is that the button doesn't light up--but that isn't much of a problem because you can see the state of the bassinet from the app. I replaced the bearings and also the rubber o-rings not long ago, and there has only been about 3 months of use on those parts. It swivels smoothly and quietly, just like new. It includes the original mattress (pad), a thicker mattress, five sheets, two small-size swaddles, three medium, and one large. Price is firm. These go for ~$1,200 normally.
Also, if you have a Snoo and it's making grinding noises, I now know how to fix that and can help you out. :)
