Summary: My first version arrived with the column platform broken. Sent it back and received another a few days later. I have been using the tripod to support a 400mm 2.8 which it should have no problems doing. However after about a week on tour in the desert, the platform once again cracked...I think it is made of some sort of cheap alloy. It's unfortunate that this product is distributed by HP Marketing, as their customer service isn't really ...good.
Pros: Easily Adjusted, Good Footing, Lightweight, Locks In Tight, Rugged
