Product review (4 stars): Good set of bags
I've only used one of the smaller bags in the washer so far and it did a great job of keeping my undergarments together, which led me to decide to just put the bag as is in the dryer.  The bag held up well, but the contents didn't dry like I was hoping they would, so I had to rerun them without being in the bag.  Minor issue, no big deal.  The only thing I really had a problem with was the string to close the bag is really long.  I had to tie it quite a few times to shorten it so it wouldn't get tangled in my washer.
