I love this thing!! It's actually the 3rd one I've bought. The first two were but through the wringer for sure!! When my baby just can't soothe himself to sleep or is overly tired or just refuses to calm down, I pop him in his crib and turn this bad boy on and with in 5 minutes BAM night night baby!! Now all babies are not made equal, if that were the case this would be a boring world to say the least, so this may not work for your baby. I will tell you that this new one is different from the previous 2 as it only has two settings, on and off, the previous 2 had a strong and soft setting ... along with the on and off.
