The Gypsy Gripper

I think it's safe to say that I'm in NEED of one of these, rather than it just being a want!

"The Gypsy Gripper has a comfortable grip handle, and two large round suction cups with handy lock & release levers. Just press the suction cups to any plastic ruler with a smooth solid surface, and then flip the levers to lock The Gypsy Gripper in place. Now you can move the ruler quickly, and easily hold it on the exact position with gentle downward pressure. Your ruler hand will be up and away from the fabric, and out of harm's way if you slip with the cutter. When you need to switch to another ruler, just flip the locking levers to release The Gypsy Gripper."

By chance do any of you use The Gypsy Gripper? If so, I'd love to hear your thoughts/review of the product!
