Unfortunately done too cheap

First of all:
I was looking for a cheap ball head but also a heavy camera and lens can hold easily and stable (a Canon EOS 5D Mark II + corresponding lenses in my case). When searching, I found the Bilora Perfect Pro.
The unpacking was a surprise at first but gratifying: the ball head appears wertig, you have quite a bit in hand. The pan and tilt functions ran clean, and there was little to complain about. For the price a seemingly good choice.

It was clear that the difference in price to a quality ball head had to come from somewhere. And so, unfortunately, too many points stood for half a year now as poor out:

- The locking screw for the rotation function is defective despite a moderate use. Meanwhile I carry in addition to the equipment with another forceps, so that I can turn the screw.
- In particular, the portrait, the camera hangs permanently down. Since I mainly do landscape photography with the head that is very annoying, and the water level to the hot shoe does not help much when correct setting
- The same applies to all other positions (other than the defective Schrabe for the rotation): When tightening the fixing screws of the ball head moves to something so dasss you possibly have to correct here several times..

Conclusion:
I'll replace the head soon and would rather pay twice. Who is really looking for a high-quality ball head should invest liebr a few euros more. But if you first of all looking for a really cheap option, and can get along with the above-mentioned problems, can find quite a good interim solution. As much more I can Bilora Pro however not call.
