OnGuard Bulldog DT 5012

It's a fantastic small U Lock. It always stays attached to my bike when I'm riding and apparently has a lock system which is very hard to pick. The only reason I gave it a 4 is because of it's length it… doesn't lock to as much as a larger U lock would. I wish it was a tid-bit larger. (Note: I ordered the regular Bull Dog U lock and it was way too big and heavy for my bike. I wish there was an in between but the small lock does the job)

The key on this product has a thin area right above the notches that fit the tumblers. In my case, this caused it to break off in the lock earlier today (I did not apply excessive force, knowing from… experience the hassles a broken key can cause ). Now, the only way of getting my bike off that stand is for me to go home, bring back my rotary tool and cutting disc and have at it (if that works, this thing is hardened steel) . The lock itself might be as safe as the Bank of England, but I would advise against buying this product because of the key. Update: the "13mm hardened steel shackle" on this lock took about five minutes to cut through with my little-bitty cordless Dremel, so I shudder to think how easy a job it would be for any thief with a "professional" tool. In retrospect, I am happy the key broke off and that I had to get rid of this lock.

So I thought I was buying the Pitbull DT and was a little unhappy when this arrived. In any case, I didn't want to hastle with returning it and I've been using it for the last few weeks. My reaction is… that it is a more than effective lock for low crime areas. I live on a college campus and I actually have had a bike stolen. That was my fault though, as I left it unlocked while I visited a friends house. People here lock their bikes up with cheap cable locks and U-locks from Walmart all the time. I get the sense that as long as it's locked up with something, it's pretty safe. I know that's not true for all areas, but the Bulldog DT has been extremely effective for me.
