(From an email. Please note that we do not answer questions like this via email. Please post as public message.)Priced between $350 and $500, depending on options, this is probably the cheapest camera jib out there. It is adjustable - either 8 feet or 12 feet. I've been using one (earlier model) for years and have been very happy with it, but I understand its limitations.
This is a lightweight jib (sometimes called a "camera crane", though technically we don't give the "crane" designation unless it also supports an operator.) and is great for stationary shots with a wide overview - of a reception dance floor or other event, etc.
What it does not do well is moving shots. Why not? Well, as noted earlier, this is a lightweight jib. Its arm will flex and "wobble" as the concerned writer of this email has noted.
So, if you want those "flying camera overhead" shots, this is not your jib. Expect to spend several times the price for a solidly built jib.
If you want a stationary mount for a camera above the heads of guests and photographers (i.e.: unblockable), with a wide shot you can count on to glue your handheld shots together, then this is an inexpensive way to go.
