We chose the Castle for a garden shed, so that we do not always get the key. The castle is very robust. That the lock can only be opened by pushing on the metal part, we find great because so even with proper combination the lock appears closed. The bar at our cabin begins to scratch the lock something, but that's ok for us
Point deduction, there is only binding for the numbers. This example is to rotate with garden gloves not easy. Hopefully here ABUS improve the product.
