On the plus side it is relatively light to transport .
Negative points are the seat belt doesn’t flow freely through the shoulder attachment and I find it frustrating when placing a child in the seat .
Furthermore, to remove the seat from the car and Isofix attachments , it is an awkward squeeze of 2 buttons simultaneously on each side to release the seat .
Having said that , I’m assuming these are possibly part of the safety features, but I find them inconvenient .
