I've never taken the time to review a purchase that I've made, so hopefully that helps to say how strongly I feel about absolutely loving this chair! My son has loved this chair basically from day one. He's five weeks old and therefore isn't really into the toy bar right now, but I'm sure he will be later. But he does love to take naps in it (he happens to be taking a nap in it right now). The vibration is perfect. I've only had to change the batteries once so far, but we use this chair and always with the vibration on because if he falls alseep in it and you turn the vibration off he'll notice and wake up and not always fall back asleep. I picked out this chair because I wanted to be able to get my money's worth out of it instead of a normal bouncer that they can only stay in until they're about 25 pounds, but I definetely feel like I've already gotten my money's worth out of it anyway! Awesome chair! Would recommend it to any parent!
