I will try to find a link to this pod. It's ancient but I see the same model in shops still today.
As for being sturdy as a freestanding pod it's not - at all. It will support probably 10 or 15 pounds of camera and lens with no troubles at all but if you need to use it for absolutely still shots you will need to either use the 2-second delay shutter release found on most cameras, a remote control, or a cable release. After positioning the shot you WILL get camera shake if you them touch the shutter release button manually. But actually this is true of almost all but the totally monstrous pod models.
Also WHILE setting up the shot with heavier cameras you need to aim a bit above your target for as soon and your hand moves away and no longer adds support the weight of the lens will aim it about 0.1 degree (which is kind of allot) downward from where you pointed it. The quick tension release knob on the head I put on these legs compensates for that affect pretty well though: Aim, adjust, aim, adjust, done.
