This is a very solid head with rapid release. It works well with my 4x5 Tachihara LF and Pentax 67 MF cameras. The weight is reasonable, although you could spend much more money and get something slightly lighter. This head folds up compactly on the tripod (one arm attaches to the other), another plus.
This pan head is rock solid. I purchased this pan head to mount a 20x100 pair of binoculars
on a Slik pro 700dx tripod that I own. The binocs weigh 8.5 pounds. Vibration free. I am very pleased with this item. I have not used this yet for photography but I cannot find any angle that would not work. This is a real bargin for the price. One review I read stated that it was on the heavy side. Personally, for the weight I'm mounting on it, I think the weight of this pan head is light for the weight I am expecting it to carry and be vibration free.
The MH-5001 is extremely stable, it rotates smoothly, and there hasn't been an angle that I haven't been able to shoot from with my camera on it. It is heavy, but it's not much heavier that some of the more highly price heads out there.
