Summary: I bought this ball head along with a Manfrotto 190CXPRO4 Carbon Fiber Tripod to use outdoors and in studio with my Leica D-Lux 4. This combination has been great in the studio for shooting on-body and laydown apparel shots for our online clothing business. It's a very versatile system and I've been very pleased so far.
Pros: Great build quality, QR plate is very handy, Smooth ball adjustment
Summary: I purchased the MH-1302 to go along with the Giottos MT-8361 tripod legs. The ball head looks a little small atop this tripod, but it is rated to hold almost as much weight as the tripod legs, so I decided that it would be large enough. My camera is fairly light, so I can't comment on the capacity of the head. What I can say is that this is a precision machine. Fit and finish are exceptional. The ball and all of the controls operate very smoothly.
Summary: I use this head on two tripods. It is light weight and is very flexible in application. As a light weight ball head, it is going to have a few weaknesses, but for its weight I haven't seen anything better.
Summary: This is a decent ballhead in general, it's not as expensive as the RRS ones and other more highend ones. It serves the purpose of a ballhead, the only thing I would complain is the plate does move if it's not tightened down fully. But for [$], it's not bad.
Summary: When traveling, we have to be very concious of weight. I carry a very light tripod and wanted a head for doing misc. and close-up photography. Since my camera is relatively heavy, 1D or 1Ds, and a good lens and maybe a flash, I was looking for a head that would handle both requirements, The MH-1302 is great at both.
Summary: This is a super ballhead for a lightweight travel tripod. Amazingly enough, it can handle a 1DmkIII body and 400DO/IS lens without difficulty. The only downside is a limitation in the ability of the head to rotate 360 deg - after a few rotations, the head can tighten down or loosen up, requiring that one readjust to a "half-way" position. But that said, this is a wonderfully useful ballhead for travel!!!
