The negative:
- The fastening system (where it is close to the 0/20). Having had a stroller another brand before (certainly more heavy) when the setting was done in qqs seconds, in this case it is unworthy of a brand stroller.
After 20 minutes of hard work the 1st time setting (with the child sitting in order to thus set ;-)), do not think you can re-set the system quickly. For example half season when it can be cold in the morning (with big jacket), warm afternoon (with a simple t-shirt), it seems important to be able to quickly adjust the setting, then this is impossible without s' excited. So you have to choose a setting "too loose" who will go for the two configurations.
Overall I would not recommend the stroller over this principle
