My review: When I first applied the buckle on the pram, the weather was freezing and my hand was frozen. Then I decided to do retry in a warm indoor place instead. Once my hands warmed up, it was so easy to push and apply it on the pram’s strap. I made a silly mistake by putting the clip upside down. If you look carefully at the picture above, the belt clip should look like a v shape. Inside the box, there is very clear photo instructions and I obviously did not look carefully.
