Used for only two months. Still in a perfect condition.
Works perfectly with Cybex Cloud T car seat.

**Please Note** this is compatible with Joolz aer 2.
I asked Joolz's support before about compatibility and they said I can't use adapter of aer/aer+ on aer2.

We had the baby facing us on the first two months so we removed the stroller's seat and installed the adapters with car seat. It was perfect and the stroller was very compact.
Then we moved the baby to be front facing.

IMO, it's not worth it to buy it new as you only need it when baby is facing you during the first 2-3 months.
