Bis Which give it a decent rating though its not a Best Buy. Here is the info:
"Used without the base, the Hauck Zero Plus offers first rate front and side crash protection, achieving five stars for each test.
It is a little tricky to install due to the seat belt guides being partially hidden by the cover. However, if care is taken the fitting of the seat is not likely to be installed incorrectly.
It's an extremely lightweight seat and can be bought separately or as part of a pushchair travel system. Its compatible with travel systems from several different pushchair manufacturers, and your retailer will be able to provide information regarding compatibility details.
Excellent leg support and padding add to the baby's comfort and, once the seat is fixed into the car, the buckling up process is straightforward.
The seat cover is easily removable but can only be washed by hand.
Overall rating
The Hauk Zero Plus is a good all round seat, offering first rate protection in crashes. Its overall score is still quite a way off the Best Buy threshold, however."
