Solid built but had to spend additional $24 to get around the Manfrotto plate. I simply cannot abide Manfrotto plates, the cheapest Arca Swiss is much preferable IMO.

Very solid piece of equipment! It's very very well built. Manfrotto for the win.

Good afternoon!I bought one and It arrived promptly and in good shape.It handled the weight of a 5dmk ii with 24--70mm so far.I use a super clamp but a mafer or a mathews super mafer should work just as well.One more important thing. Your camera costs a lot more than this attachment..Be mindful of how you set this up and where you place the weight .I would strongly recommend a tether and a tall glass of common sense to further protect your gear.Have a great day!
