My mom received these last Christmas and only used them once, so they’re basically new. Both are in perfect working condition. ✨ Notes: Original box + paper instructions are not included, but I’ll provide official links where you can download the digital manuals. I will carefully wrap and package everything to ensure safe delivery. I also have videos showing both devices turning on/working — just ask if you’d like me to share them.
