Absolutely hands down the best investment we have ever made...and if I am not mistaking it was like $7. We have a Great Dane and he is shedding like a madman lately. We bought the Zoom Groom and the hair just poured off. No more huge piles in the floor by his bed. It is so easy and harmless (rubber bristles) even my 3 year old brushes him.
Love these Snappis, they are much better than trying to use pins and worry about hurting you or the baby. We switched to cloth with our second child and have never been happier. Prefolds with a snappi and we are good to go! Hold very well.
We loved Luvs with out first little one and they worked marvelous. I noticed with our second that she seemed to pee through them in short amounts of time. All in All they are a great brand and I would recommend, however if you have a heavy wetter be sure to change frequently.
