DanCoTek Smart Watch for Kids Girls Boys Children Unlocked 2G GSM Phone Phone Watch with Games (Blue)

My 5-year-old LOVES this watch. She has entertained herself and her sister for hours and hours by taking pictures and playing games, and the battery has held power for several hours. Highly recommend!

It was a christmas present and it didnt start. Still not working after hours of charging. I need a solution!
