The shoe mount is traditionally built. The processing is the price rather simple but nothing to complain according to principle. Unfortunately, the locking screw for the shield is not sufficient for this to be fixed in its position. This is a flaw that limits the usefulness massively. I'm the product if possible, or dispose of return and buy a little better product quality.
Too bad if the screw would fix the screen halfway and gravity could not always move it back and forth freely in the hole, the product of the price would be good.
