Steadicam for Smartphones and GoPro
Steadicams make such a difference in the quality of the video you shoot. Based on the same technology as the big $60,000 rigs used in Hollywood, the Smoothee allows you to capture incredible video and still images without the shakes normally associated with hand-held video shot on the go, right out of the box, the very first time.
PVC's Jeff Foster reviews the Smoothee for GoPro and says "I believe it's the only way to shoot handheld with the GoPro or your iPhone."
The prices vary from $119 (GoPro) to $159 (iPhone).
