Question: Anyone have a problem with getting the head to stay tightened on the tripod?
Document: I got this product in the mail today, and the tripod itself is super heavy and feels very durable. The pan head is smooth and every thing works like it is supposed too.I did have a problem with the carrying case tho. It had a huge rip right down the side, making it useless. I have not contacted Amazon about this yet. I am very disappointed in this issue, and hope that they will send me another with out me having to ship the tripod back too.
Wish I would have found this before I purchased the exact same tripod with a different name:  http://amzn.com/B00139XOCI  Ah well, an $18 lesson learned.UPDATE:  Having used this for a while, I really regret getting it.
Amazon ain't lyin' when they say this thing weighs ten pounds - it is a beast of a tripod. I'm not sure about everyone saying the assembly instructions were unclear, as I didn't even need the allen wrenches? The head simply threads on to the support shaft in the center of the tripod, and you're off from there.
This is handy for sticking it into a grassy surface so it doesn't move.CONS:1. The head is not entirely fluid. It sticks when tilting up and down on the start, but then becomes smooth once you've begun the motion. But hopefully this will subside with more use as it breaks in.2. The bubble level is off. It seems to be set incorrectly and does not correctly show when my tripod is level. This is pretty annoying.3.
Probably the least expensive fluid-head tripod online, it's also the best value that I've ever seen. The tripod, while heavy, is solid and durable. The head moves perfectly smoothly with no noticeable jitters in video. I love the included carrying bag; it's a bit flimsy but it does the job very well. Recommended to any amateur filmmaker.
Well this whole tripod with a very versatile head is less than what &#34;good&#34; heads go for so I got this. Its very strong and solid.Some reviewers have mentioned that panning slightly sticks when you first start to turn it but I think this is a good feature so your head and camera don't screw off, besides I think this is good to teach me to plan (my shot) before I pan.
This tripod is rather heavy and would not be something you would carry for a significant distance. However, the weight is an asset when using the tripod as it is strong and sturdy. I have not noticed any issues with the tripod twisting on it's feet when panning left and right with the video head. Of course it can be made to twist by using excessive drag on the video head, but you don't have to have it so loose that it will move with an accidental bump.
This is a pro video camera tripod and is not a good fit for most consumers. If you are not a professional videographer, I would skip this product and look for something lighter like this ~2.5lbManfrotto MK393S-H Short Photo-Movie Kit with Aluminum Tripod and 3-Way Head with Quick ReleaseMost consumer video cameras are between 2-5 lbs, so purchasing a 10 lb tripod just does not make sense.
&#34;Good, Fast, Cheap, pick two.&#34; is a good way to look at tripods as well as just about everything purchased. However in this case I believe you get all three. Strength, good video head, and reasonable price.
Quite heavy, but built like a battleship. It should last a long time and won't blow over in a breeze. Instructions are very abbreviated; you'll have to figure some things out for yourself. It won't fit in the carrying bag with the camera head attached. Five stars for the construction and functionality once assembled, 1 off for the little stuff
Answer: There are three set screws to tighten using the included allen keys.Lift the center column up, attach the head, and tighten the set screws located underneat the head mounting plate.
