Having read these two reviews, I decided to take two shirts to Drop Spot for cleaning. One is 100% cotton except for elastic detail at the v-neck and the other a 95% cotton/5% spandex button-up. When I got them home, the 5% spandex shirt had shrunk so much that it can barely be buttoned. The elastic detail on the other shirt shrunk leaving the shirt looking years old (note: both of these shirts were new, purchased just weeks before). I called Drop Spot and they said they had never heard of such a thing. Beware, though this is an environmentally friendly cleaner, it's not always good for your clothes. It is a new cleaning method that is not easy to master.
Pros: didn't lose my garments
Cons: shrank my clothes, pricey, pay-before and save money gimmick
