Short and sweet: The shell does exactly what it should. The locking mechanism works great and keeps well. The shell initially smells slightly, but the flies within 1-2 days, so no problem. It also feels very valuable, and that for the price. The wrinkles for setting up must be repeated a few times, so that the initial stiffness of the lid is lost. Pitching itself works knotless thereafter. By 2 magnets sheath holds perfectly even in the erected state. Strong buy recommendation!
