I have always read to use it once a week because too much of the radio waves are not good
And your doctor also said it was okay for everyday use?
I had one and used it daily. As I got further along I didn't use it as much, but I'd had a number of miscarriages and was really tremendously anxious. I'm honestly not sure how much it helped, but it was always delightful to hear that little gallop beating away!
