To take first the positive: The bracket installs quickly and the ball heads are to use also.
And now the big BUT: the glands always dissolve, no matter how much force or violence with wearing them. Are the flashes mounted on the rails are the leverage the glands solved with ease and lightning spin uncontrollably before the lens back and forth. If you want to take pictures with the arrangement of your hand this leads to despair.
A product that does not work correctly without tuition does not deserve more than 2 stars. Photographers who do not want to tinker I advise stay away from this product can be.
