I have the double-blade Deluxe and it’s utterly amazing. It levels and torts with just one sweep so it saves loads of time and energy. My only complaint isn’t due to the product’s quality or performance but my own complacency. This past week I layed open my left index finger while replacing the blade protectors which just goes to show you how sharp the blades are – razor sharp so be careful! At $100 per blade for replacements, they must be sharp!
