I have had an issue with the last two batches of ABU simple I have bought. With the pictures below you can clearly see the mat (padding) does not extend into the front of the diaper like in the original batch. I contacted ABU and the agreed it was an issue and replaced them quickly the replacements have the same issue. I will say ABU was great to deal with customer service is top notch. These were ABU Simple XL, I don't know if the issue goes to other sizes or not. And I did not have the issue with Lil Paws or Space. I've advised them they still seem the have a quality issue with the current batch and hope they can clear it up with the manufacturer. If your a back sleeper you may not have an issues with these as they are but if your a side sleeper you really need that padding to extend into the front of the diaper as it will leak out the side very easily.
Again Great company, just bad batch of product.
