small pliers to air are difficult to insert in my bmw 3 and suddenly the carrier looks to the ceiling! plus you can not adjust in the horizontal axis and therefore can not direct it towards itself. The rack system is good but can not direct it horizontally. good quality plastic by cons. will last
for me it's not good. I had a belkin for good aeration and top swivel. more expensive but top (but spring clips have broken). for other cars that can pass.
