Details not noted in the description

One can not play chords with this keyboard. This means you can press only one button at a time.
A severe restriction in terms playing music.
Also, no volume control on the device.
These are 2 things that bother me very.

I rate it with 2 stars because it was not specified that the device can handle only one button at a time.
I'm probably just mistakenly assumed that you can play a chord with a keyboard.
Had I known this before, I would have bought it at all.

If you anyway want to play only one button at a time, but it's for the price perfectly fine.
