 Eberhard Göbel enlisted the help of TÜV Rheinland to establish the birdiepal's ability to withstand wind currents surpassing that found on any average golf outing. As you can see from the pictures below, the competitors' umbrellas had many problems with the wind speed, including tearing fabric, bent guide ribs and shafts, and general implosion. The last photo shows the birdiepal at a wind speed of 65 miles per hour, but not breaking or sustaining any damage. And while it's competitors use strong, heavy construction to survive the wind gusts, this construction also makes it difficult to hold on to in strong winds. Take a look at our Real Video Footage of the tests. If you are unable to view the video, you will need to download and install the free RealPlayer plugin.
