This could be useful I suppose...if it did not wiggle so much when I type. It gets a rhythm going and it annoys me. I de appreciate that it claps with a clamp and not a spring grip as it is held in place firmly and is not going anywhere. 
I wish that it were made of something thicker as to remove the swaying and wiggling that it does in response to my typing and every day work movements. 
I also could not get this to snap together as designed. I am a stronger man with strong hands but I could not get the curved part on one side to snap onto the peg fitting no matter how hard I tried.
I am also not sure what to do with the curved up pocket that it has...it is large enough hold something, just not sure what as it is too short to hold files or books, and too deep to hold pens or smaller items.
