Mobile solution in the correct format with small defects

The screen can be set up stable with a few simple steps. At the edges slightly wavy, but only slightly disturb. The included pouch fits well. But there is a constructive deficiency: The bivalve housing the roll screen is locked to handle height in the center with two locking hooks, but do not last very well during transport by the handle so that the canvas while lifting opens downwards and coasting. Unfortunately, there is no contact with whom you could clarify whether this is a general design flaw or an isolated incident. Will have to make an attempt at a replacement.
