Bests & Worsts Reviews from Amazon

I bought these dryer balls as a spur of the moment decision and have been very happy that I did. They are solid but soft and about the size of a large orange or small grapefruit. They are a permanent fixture in my dryer and have helped keep my laundry soft and unless I overload the dryer, they really do help reduce the dry time. I don't think they are as helpful in reducing dryer time for say, a queen/king size comforter because the dryer is simply too full for the dryer balls to bounce around much. Yes, they bounce around and do add some additional noise to the dryer cycle, but because they are soft, it's not like you've got a tennis shoe rattling around or anything, but it will be a little louder and you will hear them bumping around. An added and unexpected bonus is that these wool balls attract dog hair away from my clothing! On any given day, I have a minimum of 4 Samoyeds (very hairy white dogs) and 2 white-ish cats who are all dead set on depositing as much fur on my clothing as possible. So I know about hairy clothes! They don't leave my laundry fur-free but there is a noticeable reduction since I started using them. I have also added scented oils to the dryer balls with good success. While it's probably best to not use heat with essential oils, I wasn't using it as a therapeutic use, but more just to try out how well the scents would transfer. It works pretty good and I had scents last through multiple loads of laundry. Just be careful that the oils get absorbed well by the wool before drying or you'll be distributing actual oils onto your laundry and not just passing along the smell. Overall, I love these things. Just know that they can get all tied up in laundry and I "lost" one for a while because it was wrapped up inside a fitted sheet and I hadn't noticed it.
