-The Straps twist quickly
-The Is despite the buckled his pretty loose on the seat
-The Pillows for children has to be purchased separately, ca 25th
-The Tightening function of the belts is better thought out the Romans. Maxi must not hold while tightening well, the Romans.
+ Relatively cheap maxi for about 125 of the Romans around 180th
+ Is suitable as a second seat
Conclusion
Can buy one, but I have a Volvo driver another claim. Moreover Volvo used as child safety seat Römer. :-)
