Not really great but useable

The pop screen itself does the work that he is - not bad, but not very good.The terminal can be very readily attach with a little patience. However, the telescopic arm is not stiff enough and therefore need a lot of patience until you have brought the pop screen properly in position. Thus, as shown in the picture does not keep the pop screen for example.

Conclusion:
Dear look again whether there are better thing. In a pinch, but quite ok.
