Bests & Worsts Reviews from Amazon

The repeating pattern is hypnotic and can put you to sleep in a hurry. If you want to leave it playing continuously, just turn it on and it stays on. If you want timed operation, just select 15, 30, or 60 minutes. There are different versions of this, so make sure you get the 6 varieties of sound that you like. The SS-2000F and the SS-2000S have the best choices of sound tracks, in my opinion. Keep away from the SS-2000E if you don't want that annoying Heart Beat! PLUSES 1-Mine came with a Power Adapter included, so no batteries needed. I give it 4-stars because it does what it's suppose to do, but I can't give it 5-stars because there are a few things that could have made this product better. 2-The repetition of the sound tracks provide a smooth transition from Start-to-Finish and back to Start again. No pauses, no clicks. 3-It's easy to use, just press the button with the sound you want to hear, and it plays. MINUSES First of all... 1- I would like to have an Ear Phone Jack, so that there is the option of listening to the sounds privately. 2- I would like some longer tracks. The short tracks put you to sleep, because of the boredom of repetition, however, it would have been more of a pleasure to listen to if each track were 15-seconds in length rather than a mere 3-seconds. 3- My unit didn't look new. It had little scratches and cosmetic imperfections. Overall it's a really great product and highly recommended. For such a low price you can get a good nights sleep and wake up the next morning feeling well rested. It has a way of bringing on relaxation and removing tension, should have discovered this product sooner.
