Broken - isofix jammed
Ordered this and I’m sure it would be amazing if it actually worked. But I’ve given it one star because I can’t contact the seller - I can only return or replace. The isofix is jammed and one of the other reviewers had the same problem as me. Not happy.

Iso-fix locking mechanism defective.
The seat was defective: The isofix locking mechanism was jammed on one side - (The latch does not lift on one side so the lock cannot extend out along the teeth) which means it cannot clip into the car.A replacement was ordered and the same problem again. I accept this could appear to some that I am not doing it right but I assure you both parents and a brother-in-law are not wrong. Disappointed.It also looks like other buyers have experienced and reported the same issue on here.
