“ Keeps the seatbelt away from the child's face and helps prevent accidental seat belt release „
My son now has a booster seat but I found the seat belt always cut into his neck and in Granny's car it was on his face. Not very safe or comfortable. This small triangle shaped adjuster fits over the belt and holds it down away from his neck in just the right position. I also feel it would help to distribute the impact of the seat belt in a crash and ease any minor injuries to the abdomen or chest (I am not an expert). Granny is now after one for her car and at £8.99 from Argos I will get one quite happily.
