Product review (5 stars): Perfect for "felting" knits
Not your typical use, but for you knitters out there who "felt" items, this works perfectly for me.  It took about 10 minutes to felt an alpaca wool scarf and it turned out great.  I put the scarf in a lingerie bag so it was easy to take out and check since I wasn't exactly sure how long it would take.  My front-load washer has an automatic lock, so I wasn't sure how I'd check the timing if I used it, but with the Wonder Washer's removable lid, you can turn it off and check it every few minutes if necessary.
