I found it underwhelming especially given the price

I found it a bit difficult to use and delivering little in terms of changes to the mood. Maybe it is not meant for people with average emotional response.
Took me a while to learn how to use it at which point I have asked myself so this is it?
Expected a bit more useful functionality at this price.
