Review (5/5): This Thing Really Works!
I've used this product for over three months and I must state that it indeed does perform as advertised! The sharpener is entirely magnetic and is housed in a safe hard rubber body that protects both the blade surfaces and the hands. A Gillette Fusion Pro Guide fits perfectly in it, and I have easily experienced six weeks of great shaves per blade change. The math works with this excellent product, as blade cartridges are $16.00 to $29.00 per rack. The convenience and safety of holding the razor between shaves itself would be nearly worth the price alone. I highly recommend!
