Pros: Effectiveness, None
Cons: Ease of Use
Good but very pricey
My wife bought this for me last xmas (2018). There's a learning curve with it. Its finicky about how the blade clamps up and takes some fiddling around to get it just right. Read the directions and watch the videos online. However, once you've got the hang of it, it a very good system. The clamp up is repeatable so you don't have to go looking for your angles again (assuming you wrote them down). But you need to be careful with the clamps. If they are not clean when you clamp the blade, scratching can occur. I always use painters tape. It sounds like I'm criticizing it but really I'm not. I messed up way more blades with bench stones. The edges can come out as close to razor sharp as I've ever gotten to without sharpening an actual razor. Overall a good product. However, as you can tell from the price they are very proud of their product.
