Good Product
I find it works just as well as Oxyclean which I use also.  Didn't notice any difference between the two when added directly into the washer however, I haven't soaked any garments overnight yet which is where this product allegedly excels with white garments especially.  I didn't purchase it here on Amazon as its a grossly overpriced rip off (all sizes).  Target sells this 80oz size for $5.99 and you can find a $1.00 off coupon at the manufacture's website to further reduce its price.  Its well worth that $4.99, but certainly not $25.99, do not reward these unscrupulous rip off artists.
