Summary: This car seat has been the recommendation from the manufacturer of our car. But it needs the tether and this makes adjusting the seat into its different positions very complicated, so we always have it on the same setting. It needs brutal force to change from upright into more comfortable sleeping position. I also badly hurt my thumb on the buckle, but that might have been operator error, although it shouldn't happen.
Summary: Me and my partner bought this for our 23 Month Old to replace an older style Britax Renaissance car seat which doesn't have Isofix. Firstly it is MUCH lighter and with a smaller footprint than the Renaissance, which is a massive plus for us as we frequently have to change the seat between cars.
