On Wednesday I bought 4 FPSVB for his car; Friday they arrived and I thought WOOO HOO!!! I was bummed though that the DOM on 3 of them were Jan 06 while 1 was Sept 07. Anyhow, yesterday we sat down and attempted to put them all together. The one is broke. It doesn't snap in and the back of the seat doesn't stay upright. It falls right back down. None of the other 3 do this. So now I'm kind of bummed I'll have to call them on Monday and try to get this straightened out. It also makes me wonder if any others are out there where people might have bought one and don't have anything to compare to and think it's normal? I know it did raise my eyebrows as soon as it happened but others might not think they got a defective seat from the store. KWIM?
