This is a handy device and you can tell some thought went into it. However the brushes are best used when the computer has shut down rather than when in use, which is why I am giving it four stars instead of five.

It’s more awkward with the attachments. How do clean the cloth after using? It does the job

This is perfect for anyone working on a computer at home or in the office. I bought mine for in the office due to all the dust that gets in the keyboard and was shocked to see what all came out with this. I love it and I suggest it to anyone trying to keep a clean environment.

Didn't serve the purpose. Both brushes didn't even reach the bottom of the keyboard. Will be returning the other 2 that I bought.
