MJM, it's one of the most innovative inventions since someone discovered you can use a bent pair of scissors to pull unsightly hairs out of your nose.. It's a seat, with a mirror on it.. You stand over it and take a photo of it, therefore taking a photo of the reflection of your ass. Umm.. or you could just stand over a mirror. Or you could just not take a photo of your ass.. I guess this product caters for a niche market.
