My child used the old safe and sound child seat from a friend. It still last another 4 years until he need to change to the booster seat. So safe and sound is the top choice from mother father and the kid. Search on google and come out lots of cheaper brand but need to shop physically to buy good and worth every cents product

We purchased this to compliment the "Tourer" booster. We felt he was a bit loose and unsecured with the lap belt alone so added on this harness. It's a bit fiddly to figure out at first but once you've gotten used to it, it's easy enough. It made the booster feel sturdier. Boys are always trying to undo their seat belts so this was a great addition.

A bit fiddly to install the first time but we now move between two different cars with no issues. Great for my son who still falls asleep in the car and slumps forward, this reassures me that in a crash he won't slip out particularly as we go driving in the bush. We plan on buying a second one for his brother.

I hated it and returned it to the store. It is hard to get on not safe and uncomfortable for the child

I love that fact that the belt doesnt sit under my childrens neck and it was easy to use. I watched the dvd to install first then installed in about five minutes. It did take a bit of getting use to buckling it up but now my kids are use to and they buckle it by themselves and i supervise
Relible, practical
If you have 3 car seats in a row it can be difficult to buckle. ( but impossible)

The harness provides much more protection than a adult seatbelt, and I can't find any other brands providing a product to compete with this one - but it is expensive, very complicated, very slow to buckle in, and I I think most people will give up bothering to use it ..... and at the best it certainly wont get used 'properly'. Good idea, terrible design. Instead of using the aducte seatblet acorss the child, they should just use it to hold the seat in and use a separate 5 point harness built into the seat like those for younger kids.
Safer than adult seatbelt
