Efficient but loud!
I've never tried these before, but they had such great reviews and the lack of needing to go out and buy dryer sheets was worth it. I toss three into the dryer, two on the bottom and one on the top of the wet laundry and that cuts down on the thumping of them. They're a bit loud and take some getting used to, but they do such a great job at shortening the drying time, that the noise is worth it, even in an apartment with thin walls and insulation. The sound is similar, though not as loud, to tennis shoes in the dryer, if that gives you an idea of what to expect.<br /><br />I totally recommend them! They do what they're supposed to, and these in particular come in a nice touch to keep them all together.
