I purchased 80 of the b grade tykable cammies blue diapers. Overall there the best bang for you're buck considering there ultimately getting thrown away. Overall they do there job and more of a cost effective price. Like the add states on the website the waistband is either to tall or short in the front or back, or other cosmetic imperfections. I found that typically the waistband was always cut short in the front. This was annoying when try to get it on and lined up. I did have some that had bad velcro tabs that pulled right off. So I taped it on like Magiver would. Overall they do there job at a more cost effective price point. I think my next order I going to try the regular not b grade for comparison next order.
