Summary: Good lock, small size can be a problem
Comment: I purchased this OnGuard Pitbull MINI DT 5008 lock after extensive research on the best locks and locking techniques available. I decided to use the Sheldon Brown method, which requires you to lock your back wheel to a rack or parking meter, making sure you pass through the rear triangle of the frame. A mini u-lock is recommended as it is harder for thieves to work with. However, the lock is so small that, depending where I can find to lock up, I can't get it to close using the Sheldon Brown technique and have to lock up somewhat more insecurely. The cable, while not capable of doing battle with a bolt cutter, is great for locking down my seat post - especially comforting given the rash of bike seat thefts in my area. The 5 included keys are handy so I can leave one at work, home, carry one, etc. Overall, a good value and exactly as described. I just wish I had bought a slightly larger lock given the dimensions of my bike/wheel and what I have to lock to.

Summary: Small but tough
Comment: I got my MINI PitBull over a month ago, after shopping around and reading numerous reviews on different websites. I was looking for a reliable, well made lock that would not be too heavy or too bulky or cost a fortune even though I do have a nicer bike... And that's exactly what this lock turned out to be. It's fairly easy to mount and use, the mechanism is smooth and the cable provides lots of options for locking. Feels pretty solid overall, a good buy for the money

Summary: easy to use
Comment: Big heavy lock plus cable means thieves will look for easier targets. They give you plenty of extra keys. I keep the lighted LED key on my main key chain, and the spares attached to various bags that I use for commuting, in case I lose the main key.

My only minor criticism is of the flimsy bicycle mount, which really can't support the weight of the lock. Attaching to my frame that way will just result in a noisy ride while the U-lock flaps around and bangs against my bicycle. It might work for some frames where it's possible to hang the lock upside down, instead of mounting it horizontally, but on my small bike that isn't possible.

Summary: The lock is solid, but a bit shorter than needed
Comment: The lock is solid and pretty heavy. The attachment to the bike is easy. However, I found it to be a bit short for some parking places. The wire that comes with the package is pretty handy for locking the wheels.

Summary: Great lock!
Comment: Big, tough, heavy looks indestructible and comes with insurance.
I think it was a bargain.
