Very relaxing, effective
So far, I have only used it in the first mode with massage and music. I have not tried the heat settings yet, I will give that a try once I have figured out the somewhat cryptic and limited directions. This is one of those "you have to know how to use it to know how to use it" things. I still have no idea why there is an optometrist's eye chart included in the box.  I would give it 5 stars if the instructions were more understandable. Also, the music is quite pleasant, so I will not be connecting the Bluetooth to any other streaming audio, I'll be using the included one instead. And the recharging is via an included standard USB-mini (Android style) connector but they do not include a charger per se, so you have to use your own or charge it from a computer.  I'll post an update if I find the other features worth mentioning. As it is, I recommend it.
