Query: Easily broke.

It's a great concept...and if you don't put a slightly too-big pen/pencil in it, it works great! Unfortunately, it does not withstand much pressure and the pencil-grip piece broke in the first week. If you never plan on stressing it, it'll work great. It holds the pen in a great position; a fairly "normal' position. The company did offer to send an immediate replacement, however.
