I spotted the above device in a local Target store last month and had to go online to figure out exactly what it was:
The 4moms® mamaRoo® infant seat bounces up and down and sways from side to side, just like parents do when comforting their baby. Select from five unique motions (car ride, kangaroo, wave, tree swing and rocka-a-bye) and five different speeds. Choose from four built-in sounds or connect it to any MP3 player.I'll defer passing judgment; I'm sure there's nothing that can go wrong and that it's secure from hacking.
The adjustable seat reclines to any position for maximum comfort so baby can lie flat to rest or sit up for play. The mamaRoo is Bluetooth enabled so you can control the motion, sound, speed and volume from your compatible smart device!
Keep baby’s attention with the toy mobile which now includes interactive, reversible toy balls (mirror, rattle and crinkle toys).
