I know there was a detailed review done on them recently. The test was very positive. They are on par with Bambino Belssimos as far as the test shows.
As far as spending the extra money, would be up to you. It is a themed diaper, that has a crazy capacity. Maybe you should buy a sample before making a large investment and decide for yourself if you think it's worth it. I also would suggest purchasing cases rather than packs, it's cheaper in the long run and that goes food all diapers.
