Query: Impossible to secure seat base

This care seat is impossible to safely install. I purchased it for my third child and was desparately looking for a narrow infant seat to fit between my two other children's boosters. The thin profile seemed like the perfect solution, but there is no way to securely install this base. I've been dealing with car seats for seven years now and have never had a problem securing one.... especially with the latch system. With this seat, the base will flip up and slide off of the belt as it is tightened. Even at it's tightest point it can be easily wiggled out of the belt by hand. Combi has a narrow infant seat (but their buckle is EXTREMELY difficult to latch). Now that I have a minivan, I returned to Graco. I highly recommend their infant car seats.
