I have used quite a few and while the capacity is OK (certainly not in the Premium class) the tapes are TERRIBLE!! Sure, they stick just fine to the front when you tape up, but where they are attached to the back wing they will often come completely off the diaper! And that's just trying to open them up from their as-made position. Hey, I know about this problem and really try to go easy with the tapes, and they still come off way too often.
BTW... I'm pretty sure the "Smartcore" name is just a marketing tool, nothing really new and in my opinion they're not even as good as their ATN's.
