I finally had a chance to try the sample of Purex Complete Crystals that I was sent. And my verdict is...I like it. I used it in one load of laundry and found the end result to be fluffy, lightly scented towels that were a pleasure to use after a shower. I used it in conjunction with my regular laundry detergent and didn't add anything else in either the wash or the dryer (although I did use dryer balls).
I don't like how strongly it is scented right out of the bottle - it stunk up my small laundry room. Not a fan of that. I don't think it's a necessary product - white vinegar is chemical free, cheap, and just as effective in softening clothes. But as I said earlier, I do like my towels to be fluffy and to smell good, so I probably will buy Purex Complete Crystals in the future to use in those laundry loads instead of using a dryer sheet or a liquid product that could gunk up my washer and reduce the effectiveness of the towels. I don't see myself using it on my clothing on a regular basis, but perhaps I'd use it in loads of just jeans or just certain other pieces.
I wish there was an unscented, color-free version - it looks to me like it could just be sugar, clay, and peg disterate and it would work just fine. But yes, in general, I liked this product and felt that it did what it promised. I don't know that I would've tried it at all without being sent a free sample, so the marketing also worked. Sneaky sneaky.
