I like the various sounds. Thunderstorm is my fav.
PROS
- compact size. It is small, and I was sceptical a first about sound quality.
- battery and AC powered - can be taken anywhere, or plugged in the regular outlet. Since it is 110 V, you will need adapter if used in another country, or you could use the batteries.
- quite loud on highest setting - I was surprised that such small machine can produce such a loud sound.
CONS:
- the only one I can think of is that sound is bit distorted at higher settings - I guess it depends on the size of the speaker.
Overall, I am happy with this purchase.
