David,
Just looking at the basic design, what first sprang to mind was that the connection between the legs and the main pier section right in the middle of the pier looked to be a weak point in the design - at least to me - but I should say I have no experience at all with this product.
If you are relying on the cables for your rigidity, then I would imagine in the wind the system would vibrate around a bit - the wall thickness only looked like about 2mm or less.
I am not sure what advantages this might have over a good tripod other than it seems to pack very neatly into a short cylindrical pack and whilst that is very appealing the basic purpose shouldn't be overlooked.
Its only rated at a 15kg weight payload and is itself only 6kg - so it may be a bit lightweight for anything serious - I'm not sure what mount, camera and OTA could come in under that restriction.
But I guess its almost cheap enough to try.
I wish my portable pier was that portable !
Just my two bobs worth
Cheers
Rally
