Beautiful house with weaknesses

We have reviewed the previous seat of Cybex for 2 years in use. This is characterized mainly by 3 criteria to evaluate areas: security, price, service and function. The seat is easy, safe and handy. Our daughter loves him. If we leave only these 3 depreciation areas, then we evaluate the new headquarters worse. It is more expensive, heavier and bulkier. But he has an extended side protection system, should therefore be safer.
Among other things, the new belt guide is located so that it no longer automatically unrolls, so constantly hanging in the car inside or out the door. High aspect, side impact protection, one is forced to be extremely contort to bring the belt into the lock. This one is compelled to adhere to the inner Styropoor - supporting wing of the seat, which will lead sooner or later to the break. The old seat could be served by the child itself easily. With the new: "None".
The seat should be safer. We have, fortunately, can not check.
A nice seat, but in direct comparison ... everyday, with some drawbacks and weaknesses in the operating practice.
