At the first step, unfortunately, the front pillar was caved in at the level of the lowest level strongly inward. Maybe a Transporschaden, I thought, and ordered a replacement.
The second had experience this issue then the same on both sides, ie left and right at the level of the lowest level. In addition, the middle two support rods were used twisted, so that the impact is not as planned be put together to save space, but also needs more space than without this additional kink in the two bars. In addition, the rear part of the passage was completely distorted, the gap size when folded kick differed from the left side to sechten a few cm.
Unfortunately, that was still not enough of the good. I made the mistake and looked more copies of this passage in the local hardware store to. Again, with all five existing copies of the tread at least a foothold at the level of the lowest level was strongly caved inward.
Unfortunately, the quality control of the company Hailo for this step seems to work in any way. Lack brand alternatives I'm going to grab well on a no-name product from the local hardware store back. The cost is less than half, I can sometimes turn a blind eye.
