really got result
So I've used this product a few times, and I have to say that it works better than expected, and the amount provided is very generous; this could easily last months. There isn't an appreciable negative taste. However, the product itself is very messy; expect to get fine black powder around your sink no matter how careful you are, and expect it to take a bit of work to get all of the black out of your mouth following use. However, that's a somewhat difficult problem to get around with this sort of product, and I think the consumer knows what they're getting from the images, so I don't suppose it warrants removing a star. If you're okay with the mess, and don't mind additional brushing time, I would recommend this product.
