I got this as an early Christmas gift for my grandmother who sometimes has trouble sleeping. She doesn’t like to take medicine and she had a machine like this years ago so I thought I would get her one. My grandmother absolutely loved it she said the sounds were soothing and calming it helped her fall asleep. She also likes how it’s portable and works by plug in or batteries. If you have trouble sleeping this is definitely the product for you or if not for you it makes a great gift for someone!! So this product is a must!!
