Bests & Worsts Reviews from Amazon

I recently purchased these "Washer Laundry Balls" off Amazon. I was SOOOO skeptical but kept hearing great things. My husband works an extremely dirty job, so I figured I'd test these on the toughest load. I used NO detergent...just two of these balls. There were two pairs of jeans several work shirts, socks and underwear in this load. All were filthy. Here are my results fresh out of the washer. I'm pretty impressed! I am also impressed there's no smell. They smell fresh...and his laundry never truly gets rid of "that work smell". I do want to mention that his stained clothes were still stained...but anything with new dirt or grease was spotless. On my next load, I washed towels. Again...no detergent. They came out smelling like nothing!! No "wet towel" smell, no chemicals....Nothing! I typically have to watch my towels with vinegar to get them this fresh. I'm sold!!!!
