I bought this for my baby girl and am really pleased with my purchase. Excellent quality and customer service. The clasp on the bracelet we initially recieved kept coming loose and fell off of my baby while we were at the store the first day she wore it. I emailed the seller and they responded quickly and shipped us a replacement without a hassle. Highly recommend. I definitely notice a difference in my baby's temperament when she wears this product vs. when she's had it off for a couple of days. She sleeps better, doesn't spit up as much, and doesn't drool when she has it on. I have nothing but good things to say about this product and this company. Will be purchasing more products from them in the future.
