I like the keyboard and it's quieter than the returned keyboard. However, I have a feeling that this device has been used. Fingerprints are everywhere on the device. I was disappointed to see this. Also, NO INSTRUCTIONS were included. I went to the site and everything is in a different language. There was some English but not enough to help me. I was able to return to the product on Revain to see that there were some lighting instructions posted there. I shouldn't be looking for it there. Overall I like the product but would have liked a new unit (which I paid for) and instructions.
