Yes, first a screw cover fell off, I didn't find where it came from, but I wasn't concerned about it. Then a red loop hole I was supposed to position the car belt through disconnected from the screw fastening it to the car-seat. I immediately took it back to them and asked to cancel my credit card payment and left.
The link you posted is scary!!!! How am I supposed to know if what I bought is genuine? What should I look for that any plastic manufacturer can't fabricate? The sales woman said it was French, but it says Sigma on it, the booklet that came with it says Nania, the booklet has lots of languages in it and the English was okay, but should that really be the sign that the seat is genuine? I did buy it in a respectable store.
The crash test shown in that video has me feeling that the straps should be the original car seat belts and not the car-seat straps. I also feel that the sideways range of motion is a lot bigger than in the previous car-seat. Should I be concerned about this, is there anyway to fasten the seat like the other one (it had an additional loop on the top back, this one goes to the sides and around and downwards.
