Pros: small and compact so good for small work area nice and bright back lighting

Cons: back-lit keys do not turn on with computer, you have to manually turn them on every time. very loud keys. loose USB connection, sometimes disconnected when i moved the keyboard.

Pros: none

Cons: speaker came loose after about a month of use. tried to reinstall with glue but did not last

Overall Review: sound quality was fair but not with the price.
