Fly Cam did what I needed and stayed balanced throughout the day during recording. However. Fly Cam is a cheap design. The screws are plastic, the case won't last long and I'm afraid the camshaft will fall apart causing the mechanism to fall to the ground. Probably bite the bullet and buy a better sliding cam. If you are on a budget this will work. Note, however, that this product is unlikely to last more than a few shots.
