Not only that, but they're far more robust and as close to pick-proof as is possible for a mechanical lock. You can pack mud in one of those things and it'll still work. No return springs to break or wear out; the key itself resets the wafers to neutral when withdrawn. Lastly, it uses the side-bar system similar to Medeco and General Motors locks, so there's no sensory feedback to allow picking. I also like the fact that it's a Canuck product.YBut they seem more secure because of the 3D nature of them (it looks like various surfaces on the key are utilized).
