What to know before buying

Listing details to confirm

The listing gives the maximum load as both 2 kilograms in the feature description and 4.4 pounds in product details. Treat the lower stated figure as the prudent limit unless the selected listing confirms otherwise. The listed item dimensions of 0.57 x 0.31 x 0.14 inches also appear inconsistent with the stated 9.8-inch arm length, so confirm dimensions if they matter to fit or transport. The tabletop mount label does not rule out the separately described clamp mounting on poles, posts, tripods and tables.

Who is it for?

A good fit for

Camera and accessory users building a static tabletop, pole or post setup within the stated clamp opening range.
Buyers attaching compatible equipment with a 1/4-inch interface, or who already have the required adapter.

Less suited to

Cycling, vehicle travel or other dynamic camera mounting, which the manufacturer explicitly advises against.
Buyers needing a confirmed load limit above 2 kilograms or a specified weather-resistant mount.

Customer feedback highlights build quality and versatility as strengths, while reports about stability, clamping, adjustability, durability and weight capacity are mixed. Some customers say the mount grips securely, while others report slipping or ball joints that do not lock tightly enough. For a static accessory setup, that makes careful positioning and checking the joints important, particularly given the manufacturer's stated 2-kilogram limit and warning against dynamic use.

Positive themes

Customers describe the build quality favorably and appreciate the mount's versatility as a field-kit accessory.

Mixed feedback

Feedback on stability and clamping differs, with reports of both secure grip and slipping.
Some customers report that the ball joints do not lock tightly enough, alongside mixed feedback on adjustability, durability and weight capacity.

Frequently asked questions

What is the stated load limit?

The feature description specifies a maximum load of 2 kilograms, while the product details list 4.4 pounds. Because those claims conflict, use the lower stated limit unless the listing for your selected item confirms otherwise.

Can this be used on a moving vehicle or while cycling?

The manufacturer says the arm is intended for static scenes and advises against cycling or use with heavy cameras during vigorous movement.

What mounting interfaces does it have?

The feature description says both ends of the arm have 1/4-inch screws. It names GoPro, DJI and Insta360 compatibility only with an adapter, which is not included according to the listing.

What surfaces can the clamp attach to?

The listing describes mounting on poles, posts, tripods and tables, and gives a clamp opening range of 15mm-55mm. Check that the intended surface fits within that range.
