I've 3 carseats in total........2 Combi and 1 is Everflow, as Lok Lok is getting big, he like the carseat which can sitting upright and without the 5 points shoulder hardness.
Vote for Maxi-cosi and Britax in consideration of safety.
The Ferrari is OEM by a France-based manufacturer, Team-tex, of low-end baby gear. Better do a bit of research about Team-tex before you go for the Ferrari.
Don't worry about your carseat. I was not saying team-tex carseats have any particular serious defects. I believe some of those who want to buy the Ferrari carseat think it is really made by the renowned car manufacturer. I just want to alert them not to project the reputation of the "car" to the "carseat".
In terms of the design and safety mechanism, Team-tex is not comparable to high-end products but its edge is with the price. Overseas users are more concerned about the level of protection as they often travel on highways. It's good to take a look at their reviews though their experience may not be totally applicable in Hong Kong. At the end, it is the user to decide how much protection he/she wants.
Frankly, Ferrari is more expensive than other Team-tex carseats, obviously because of the brand name it carries. As long as you deem it value for money, its fine.
