Review (4/5): don't forget to take off the film over the mirror!
I didn't notice this little detail until after I wrote a negative review: 'Not a great product. "Mirror" is not clear or very reflective. Difficult to clearly see your image, and not good for seeing detail. in the cloudy reflection.' Glad I figured this out and could revise this review.
Bottom line: it's a good product, I'm a dummy.
