portable DVD player (Markinch KY7)

I wonder if anyone has a portable DVD player that they no longer use? My Mum lives in a care home with dementia and I had old home movies put onto DVD years ago. Unfortunately my old laptop tops DVD player no longer works but I would love to be able to play Mum some of the old home movies and I thought something like a portable DVD would be idea to take along and show her fro time to time. Many thanks for taking the time to read my request and if you could help it would be really appreciated. Thank you
