Rob 5 This ball head mount is a great tripod head. The low center of gravity makes for a more stable platform which feels very useful when using it with longer, telescopic lenses.It is a very large head, so isn't that light weight, relative to smaller heads, but I don't think you are buying one this size for a light-weight setup.I found it to be very secure even when angling the mount for vertical shots. There was no movement once the lock is tightened.Whilst not a cheap ball head, I think the price is great value for the build quality and secureness that it provides.
