Terrible experience ! I ordered 4 books & 2 out of the 4 , more specifically “Twinkle Little Star”, didn’t work even after fully charging them. I was sent 2 replacement books & they don’t even work after fully charging them ! Now I’m stuck with 4 books that don’t play & I’m out money that I paid ! Cali’s Books are dishonest crooks. I’ve now tried to reach out to them for the nth time via emails & no response ! A huge red flag too that it goes straight to voicemail when calling customer service !
