OnGuard's Bulldog DT pairs a tough-as-nails U-lock with a sturdy steel cable for increased security. The 1/2-inch hardened steel resists cutting, and OnGuard's stout X2 double-bolt lock mechanism is pick, drill, bump, and pull-resistant. Plus, the included cable is 4-feet long so you can lock both wheels and the frame without any bike disassembly, making lock-up faster, easier and more secure. This great U-lock also comes with five keys, including OnGuard's Microlight key which has a built-in light.
Great product that gives you a sense of security knowing that your investment will still be there the following day. However, the carrying component you install onto your bike does not hold such a heavy monster very well. Twice the U-lock came off its carrying component when I hit a few bumps on the DC roads. Thank goodness the U-lock didn't hit a car or pedestrian when it fell off. Overall, it's a great product, but it's carrying component can be improved. I now carry the U-lock and cable in my messenger bag.
Bottom LineYes, I would recommend this to a friend
