I have been using them for almost a year now and like them a lot! I still use fabric softener for my towels. The reason I bought them in the first place was to use them for pin cushions - wool makes the needles glide thru fabric so easily - but then read what they are supposed to be used for and gave them a trial. I was shocked how well they worked without any perfume smell and used ever since. I can't say they really make laundry dry any faster.
