Good build quality, length of cable is ideal for general use, and as its not coiled, like so many are, so it does not put undue strain on the hot shoe through always being under tension.
Hot shoe mount is metal and stiff to use, this may get better with time, but at least its not going to fall off easily.
The previous reviewer comments upon wireless control as a better alternative. Yes - true if you have lots of money and need more than getting the flash unit away from the worst place you can have it.
I would prefer not to compare the two products as I think they perform different functions.
This lead however is easy to transport in a back pack, requires no further power sources to make it operate, has no further set up other than connecting it to the camera and the flash unit, and is an ideal partner to one of the 'strobie soft box on an arm' products that are becoming more readily available.
