The quick release system is unique to Trek-Tech's line of products and is known as the "MagMount STAR, an acronym for "Square Tooth Anti Rotation" according to the company's web site. The manufacturer's web site says the ball head can support up to 9 pounds. The T-Pod comes with its own carrying bag.
The system is practical, relatively easy to use and the rare earth magnet head makes what seems like a tiny attachment point very secure. Keep in mind though, you need an Allen wrench (supplied) to attach and remove the quick release foot from your camera's tripod socket.
