PLEASE READ DESCRIPTION Used about 3 years ago with my daughter- no longer have a need for it. As seen in pictures, it plugs in and appears to be charging- have not attempted to connect to our wifi or collect a reading with it since my daughter stopped using it. Smoke free home. Some minor staining on sock as seen in pictures. This is the Owlet 3rd generation (older model)- current version is the owlet dream sock. Open to reasonable offers- a great way to have some peace of mind with a new baby! Was stored safely in original box for the past three years. Cannot guarantee how well it works now since there are new ones on the market- BUT it does turn on and charge!
