We're getting ready to purchase our third...
The proof is in our purchases...five years ago when my first son was born we purchased this soundmaker.  When my second arrived two years later, it was a no brainer that we would purchase another.  These soundmakers provide just enough white noise that it covers up extra sounds (barking dogs, siblings playing, etc.).  My fourth child is due in July, so we're getting ready to purchase our third.  The first one was purchased five years ago and is still going strong. We are very pleased with this product as you can tell by our loyalty.  I recommend this product with no hesitation.
