The handle of the triangle is only loosely and needs to be used. This requires a bit of skill and strength. Unfortunately, the plastic of the Geo-Dreicks the pure pushing the handle has at this point a small crack get (about 10 mm). Basically the Gebrauchstaublichkeit is thereby not be harmful, but I'm not sure if this plan does not expand over time and the triangle breaks. Triangle was reclaimed and a day later before the replacement get (respect!). Here, however, the same problem. Both triangles go back. Too bad.
