I wanted to let you know how pleased I am with the Sound Oasis machine. I have had several machines in the past that I was dissatisfied with. This was the answer I was looking for. The sounds on the machine are authentic and real sounding. The one touch button is great and it is nice to set it for a specific amount of time to play then go off. The ability to add sounds through cards is also a big plus. I have thoroughly enjoyed it. It provides the perfect soothing environment for sleeping. Your product rocks!
