Nice Seat, but far from perfect!
My wife and I bought 2 Diono car seats, a Radian RXT and a Radian R120. While I agree with most folks about the quality and such of these Dionos, I find it very, very difficult, if not impossible, to install the seat properly. As we all know, the seat must be secured to the vehicles seat suck that there is less then 1" of movement in any direction. The design of the Diono prevents this. In the forward facing position in harness mode, the location of the belt path is so far rearward (due to the very slim nature of the car seat) that the angle of the belt is almost vertical. Without any horizontal component of the belt angle, there is no rearward force when the belt is tight. Hence, the seat can be pulled forward quite easily. And, the same things happens using the Latch system. Now, I except folks to tell me that if the belt is tight enough, the seat is secure. But all that is happening is the car seat is being sucked into the bottom cushion of the vehicles seat. In a collision, the car seat will flip out of the indent in the seat cushion. Now, if the car seat is reclined and some kind of "spacer" is used between it and the vehicles seat back, some amount of belt angle can be achieved and some amount of security realized. But really, that's what I have to so with the most expensive, supposedly best car seat on the market? And the worst part about doing that is the the whole reason to get ripped off paying such a premium for a car seat is to get an ultra compact seat that will fit in smaller spaces and blah blah. Once the bottom is kicked out forward, a whole bunch of room is lost and the kids legs are jammed up to the seat in front, just like the so-called "big and bulky" car seats. I know, I've had seats from brand X and while they may be more bulky, I never had this issue (in the same vehicle, by the way). To say I'm disappointed is an understatement. Frustrated and ticked off would be more accurate. Because, I don't have enough to do in my life then spend umpteen hours fooling around trying to get a car seat safely installed. Ridiculous. Good luck to you all!
