I like these laundry paks, they are a great alternative to messy liquid and powdered laundry soaps. There are a number of companies now making laundry soap in these packs and I have tried most of them. I normally stick with tide but I have been trying out these packs in diffrent brands. I have found arm and hammer to be very effective in our laundry. It does work pretty well with stains, but not all of them. The scent left behind is a fresh smell that lasts, but doesn't overpower or cause my son's sensitive skin to have a reaction. The price of these is more fair than some of the other brands. I use 2 packs for each full laundry load, if the clothes are pretty dirty. I think this is so much more convenient than measuring out soap and having spilled liquid soaps or powders. It works well for the price and even using two per load is still less expensive than the others. The clothes come out clean and soft, and it's well worth the low price. The packs have concentrated soap in them so it's not the same soap as what comes in the bottle. You just toss the pack in the empty washer when you start it and then full it with the clothes on top. I wash laundry in cold water sometimes and the packs work equally well in cold water. I do recommend that people give them a try, you can't beat the price and I don't feel like there is any sacrifice with going with the cheaper brands in this case. I am a brand shopper most of the time but it's always worth saving money if it's possible and still getting the same results. The bag also is child resistant, but it's still important to keep them from children because they think they are pretty cool and my kids always ask to check them out or hold them. The rubbery outside of the packs dissolve very quickly and they pop easily if squeezed.
