Tired of your co-workers barging in your office when you're on deadline or disturbing you while you're on the phone? Then I know what you need: the CubeGuard. It's a retractable banner that displays a message for when you don't want to be disturbed.

The CubeGuard comes in two varieties, with an assortment of background designs: CubeGuard Standard and Build Your Own. The CubeGuard Standard comes with a preprinted message, including "Please Do Not Disturb," "Out Of The Office," and "Working From Home." Build Your Own lets you create a custom message. Each CubeGuard fits entryways up to 50 inches and comes with Velcro and magnets for easy hanging.

CubeGuard was nice enough to send a few of us here at Gearlog personalized messages for hanging up in our offices and cubicles. Find out what we thought of these banners, after the jump.

I received a CubeGuard with a flower background that read, "Jennifer Is Busy. Please Do Not Disturb." I hung it up in my cubicle and immediately people stopped coming over to bother me. Needless to say, it was a huge hit around the office; a couple of people said they could use one, since life here tends to get a bit distracting with all the new, shiny gadgets that enter our offices every day.

However, when I was showing my CubeGuard around, I think I pulled on the banner message a bit too fast, because the whole thing came apart. I was able to put it back together, but unfortunately mine doesn't retract as well as it did before. So make sure you don't retract your banner too fast like I did, if you plan on getting one. Everyone else's, though, are fine.

CubeGuard Standard sells for $19.99; custom messages are available for $29.99. Not bad prices for maintaining some privacy.
