Offspring not a good diaper?

During pregnancy when i went to JB i stocked up quite alot of offspring diapers NB & S, as alot of mummies raved about it and most say the smell of pee or poo does reek. However when i used on my baby most of the time the smell comes out be it pee or poo. And also few times poo came out from the back. Just curious Am i the only one who thinks the brand is not as good as “advertised”? I find huggies naturemade a little better.
