Query: Didn't work

Didn't work at all. So disappointing. To give the product the benefit of the doubt, maybe I didn't use it properly, but it's hard to know given the fact that there were no instructions included. The package arrived with a big sticker on the back and I'm not even sure if directions were on the box but covered by the sticker. All in all, a waste of time and money.
