I have two, and I love them. I feel quite comfortable with my children in those seats, and they do have fantastic crash test ratings.
I seem to remember Britax recalled a while back, so the way I see it, no carseat company is without fault.
DS's Chest Clip broke about a year ago, and so I called the company to see how much a new clip would cost. As it turns out, the belt system in looped through the base, and it's not possible to replace a chest clip. The customer service representative that I was speaking with ordered me a brand new seat that matched the other one, and it was on my doorstep within a couple of days.
Like I said, great test ratings, roomy and solid seat, good customer service, etc. We've been very pleased.
