Purchased at the end of September 2022. There are no noticeable stains or scratches. Operation has been confirmed (connected to an outlet, and the lamp lights up white/see photo 3), but I have not performed the subsequent app connection, as my husband did that at the time of use. This is a used item, so I would appreciate it if you could understand this. (Returns are not possible, so please be aware of this.) I purchased this for my second child, but I wish I had bought it for my first child. I relied on this Cubo AI 24 hours a day. I was very grateful, and thanks to this, I was able to secure more sleep time than with my first child. I was able to sleep soundly at night in a separate room from my baby between 3 and 8 months old using this. I hope it can be of help to someone. I have used it with care, so there are no particular scratches, but I have confirmed that the power turns on. However, I am not confident in the settings, so please understand this. I will ship it in the packaging it came in when I purchased it. ● Features for monitoring baby's safety ・Face-covered alert (alert to prevent face covering by gauze, blankets, etc.), rolling-over alert ・Cry alert that notifies you when the baby cries ・Cough detection alert that notifies you of coughing ・Temperature & humidity sensor notification based on expert advice ・Danger zone intrusion alert that notifies you when a crawling baby enters a dangerous area ・Smart home compatible, allowing you to check on your baby from anywhere in the house ● Features for recording and analyzing sleep ・18-hour recording ・Sleep analysis report displaying events during sleep in a timeline by type ・HD night vision that clearly shows even at night ● Features useful for sleep training ・Ability to set lullabies suitable for your baby in the app and play them remotely ・Lullaby playlist that promotes baby's development based on music therapist research ・Automatic playback function of lullabies to help establish baby's sleep schedule ・Auxiliary light off specification to avoid disturbing the baby's sleep ・Two-way voice communication that allows you to hear the baby's voice and soothe the baby remotely ● Memories and monitoring features that record baby's cute appearance and first movements ・AI automatic photo & movie capture (baby's exclusive photographer) ・Up to 8 people can log in simultaneously, and multiple people can watch over the baby with the CuboAi smartphone app
