... Is well advised with this flipchart (which is ironic!). Unfortunately, the manufacturer has chosen for the detection of feet of plastic screws in a metal thread. Not a good combination! The result: After 3 times up and taken down, the first plastic screw unfortunately given up the ghost (not settled Tighten properly turned only). So the flipchart me has collapsed in the middle of the presentation. With metal screws from the hardware store for 57 cents (!!) and a Allen key is now all is well. Thanks to the manufacturer, that it works with cheap plastic and forces me to improve product ........
