 Solid LockJun 01, 2008
By Charles F.
This lock will definitely keep your bike safe. Don't be fooled by the name "Mini DT" because this thing is solid. To give you an idea, I weighed components:
U-lock - 2 lbs 5 oz.
Cable - 11 oz.
Combined - 3 lbs.
Dimensions of the U-lock:
Width - 6 in.
Height - 7.8 in.
Diameter of thickest part - 1.75 in.
Length of cable - 46 in.
The frame mount is pretty good (easy to install, you'll need a hex wrench though) and it comes with 5 keys (seems like overkill, but whatever.)
For the price and the free shipping, its a no brainer.
Get it and be done with it.

Better than Kr*ptonite!Jul 25, 2007
By Tom the Bike Guy
I would suggest before buying an OnGuard lock, visit the manufacturers website for security ratings. This specific u-lock is rated 4+ out of 5+. It has what OnGuard calls 4x power quattro locking system which provides greater pull apart resistance than their 2x system. The cable is there to allow you to secure additional items such as your seat/wheels. Before doing some research I was simply going to buy a large u-lock, but after reading, it seems the mini u-locks are more secure in the sense that they leave less room for a pry bar or jack attack. They also have the additional benefit of being lighter!

 Tight FitMay 23, 2008
By S. Fang
This is a solid lock, only bad thing (if you consider it a bad thing) is that it's just a tad too short. My bike has 2.25" tires, and the racks at school have very thick bars. The way I lock my bike is using the Sheldon Brown technique (google it), and it takes me a good five minutes to try to get it to lock because of the tight fit. This tight fit is actually very good, because it doesn't allow thieves to have enough room to stick in a bar to use a leverage to pry the bar open; however, given the amount of time I am fiddling with the lock to try to lock my bike, I probably look like a thief myself! People have successfully taken off the plastic cover off of the cross bar, which should give you more room, but then nobody will know you're using an Onguard lock. Sure you'll remove about a pound of weight off the lock if you took the cover off, but the thieves won't know that you're using an Onguard, so they'll attempt to break it, thinking that it's a cheap lock. Anyway, this is an awesome, sturdy, but heavy lock.

solid lockJan 04, 2007
By W. Lynn
-comes with extra security cable
-includes 1 year free theft coverage on your bike when secured using the lock (altho if you read the fine print, it's redeemable only if the u-lock is actually broken apart and you can show that)
-nice set of keys, including one with a light
-nice finish on the lock
-the keyhole is weather-protected (the shinier middle part rotates to cover it)
-snug secure fit (tho make sure it's big enough for your locking situations)
I'd recommend this lock for anything up to medium-high level of security.

 This Bike Lock Triggered My Latent SuperpowersNov 03, 2008
By Daria
My whole life, people have made unflattering assumptions about my strength. This little Asian girl, they think to themselves, is surely incapable of throwing that ball weighing less than 1% of her body mass. News flash: I'm skinny, not crippled.
Well, thanks to this bike lock, those days are over. After my brand new OnGuard PitBull MINI DT arrived in the mail, I was quite eager to test it out. I grabbed one of the five conveniently-included keys and stuck it into the keyhole. I turned it, pulled it out, and was greeted by a piece of metal much shorter than the one I had glimpsed just 5 seconds before.
The process of unwrapping the lock from its unusually constrictive packaging (I guess that a company that makes bike locks feels they have to protect their reputation by rendering their products immobile even BEFORE usage) had triggered an unprecedented and untapped arm strength that had been lying dormant my entire life. By applying what I thought was a normal amount of force on this key for no more than three seconds, the metal twisted until it broke, leaving the bottom part of the key wedged securely in the keyhole. Sure, my never-used bike lock has been demoted to doorstop, but $38 is a small price to pay for the realization that I can now destroy pieces of metal as easily as I can waste time on the Internet.
