I have the Manfrotto 700RC2 ordered me Videoneiger to use it on my AmazonBasics travel tripod which comes from the factory with a ball head. The head is completely made of metal, very massive and makes a robust and high quality impression. Disappointing however, is the function of the head. This is contrary to the claims of the manufacturer to a real fluid head, but a so-called friction head, rub with greased Teflon disks that together. This does not really clean pans are possible, there is always a jolt when starting. The biggest shortcoming is that the head (yes, the fixing screws I naturally resolved) extremely sluggish. There is a real effort necessary to move the head, especially in the horizontal. Here, the tripod must be naturally retained because it is otherwise rotates. The result, especially in smaller, lighter tripods also the problem that the tripod strongly twists.
I have returned the head again, because he is so useless for me. Instead, I now have the Velbon PH-368 - will cost around half of Manfrotto, but is nonetheless a real oil damped fluid head and a dream compared to the 700RC2. Since then does not hurt that he is made of plastic and slightly larger than the Manfrotto head.
