BEST SLEEP MACHINE??????
I purchased my first Adaptive Sound Ecotones (black one) because it was so highly rated, but within 2 weeks it malfunctioned, and I was not able to turn on the unit, in fact, I saw a spark at the "on" button. I returned that one.
I purchased the 2nd Adaptive Sound SE Ecotones (white one) because it had a few more sleep noise choices. However, within 2 weeks, the volume malfunctioned, and I could not adjust the volume. This also was returned.
Finally, the 3rd purchase was the charm, and I love this item. -- that is after about 2 months, the volume button malfunctioned. Very unfortunate.
Another problem is the cord. The power cord is not attached to the back, but on the bottom, which means the units rests on it's own power cord, and if it ever overheats, well -- that could be a serious problem. One that I hope the manufacturer will remedy.
The sound is superb, but this unit is not durable, and for the above reasons I cannot recommend it.
There are 2 models, the black, and the white. This review applies to both.
