Okay, so I've known about these things for about 10 years, but haven't gotten around to buying one until Sunday. I'm not lazy, I've just been in the planning stages for quite some time with this one, just ask my husband, I have lots of things stuck in the "planning" queue. Anyway if you buy clothes at the thrift store, or just want to make some of your clothes that pill look better you need to have this. Just be careful you don't cut a hole in your coat! I've gone fuzz ball shaving crazy, it's fun and practical!
