Useful, but getting used to

1) The bottom screw that holds the bracket to the stroller, you can not make really determined, at least not without using additional tools. Because the metal hexagon, which should sit motionless in the plastic to allow the screwing begins soon co-rotate. Up to a certain degree but you can still hold on to his finger, no longer. Conclusion: The holder is loose on the strut and are at every gust of wind after.

2) The black cylinder in which the umbrella is fixed is, in my opinion, too broad and / or too long. At least one must the big screen partners with a relatively massive knob not push until impact in the cylinder - the fastening screw (the top of the image) is then too short to attach the knob. Conclusion: The cylindrical holder is suitable in size for more balcony screens.

Personally, I'll keep the umbrella holder. The price was good enough tool to screw the thing I have in the house and am sufficiently technically gifted to "thicken" the screen with its own knob, also existing materials. However, those who do not feel like personal improvements has, should dabble rather for other variants.
