Warning! Chair dangerous, poor quality, poor assembly

One of the two fixing points of the chair observes an incredibly dangerous design. I can not believe that this chair is standard. If a bar (thinnest) to support the headquarters in the frame has had to disengage, then the seat (and the baby) flutters in the air and crashed to the ground. The problem is that said bar is held by a tiny plastic pieces and fragile. The disengagement of the bar is not certain but it is widely possible. It is out of the question to one of my twins in this seat, I return the items what not. I can certainly place a threaded rod and secures with bolts, instead of this very potentially defaulting bar, but it's not a me secures a chair for baby commercially available. Oh, and as explained in the comments, the record is abysmal. Make a note with photos prendraitun minimum time for the manufacturer. This would put me of the chip has the ear and make me understand the total lack of seriousness of this manufacturer. I specify that I already had a chair for my first line, and there was no problem. Regards, Thanks.
