The additional security cable comes in handy for securing the front rim or seat. I believe that OnGuard locks outperform Kryptonite locks dollar for dollar. A great example of that is the BIC pen trick of a few years ago where Kryptonite locks could be easily picked with a simple BIC pen, while OnGuard locks did NOT suffer from the same fate. OnGuard had and still has a more advanced locking mechanism. This OnGuard is an x2 locking mechanism, much better than most similar priced Kryptonite locks. The metal/plastic clip that carries the lock on the bike has been updated from OnGuard and works great. It has withstood a lot of abuse on my bicycle, is durable, and reliable.
As for the lock size, I think this is the perfect size and I have been able to lock my mountain bike at every location I have stopped. I would avoid buying a full-size d-lock as they are bulky, heavy, and make theft easier by allowing for bolt cutter leverage. The mini-DT has proven to be just the right size with minimal weight.
OnGuard D-locks are well worth the investment.
Get a D-lock and avoid locking your bike with a cable lock, as cable locks are VERY easy to cut with simple cable/bolt cutters. And by very easy, I mean it takes less than 15 seconds to snip a cable lock and steal a bicycle. Get a good quality D-lock, the best of which are made by OnGuard. For high crime areas, most owners recommend buying multiple D-locks from different manufacturers. There is a video of an expensive Bianchi with five, yes 5, D-locks on it in NYC! Yes, they are necessary to prevent theft.
Also, the mounting bracket for this lock is the best mounting bracket I have ever used. The design on the bracket isn't like older clips that were secured with a nylon-strip. Instead, the bracket is secured in a clamp-like fashion with two screws, and keeps my lock in a stable position instead of swinging around. I wasn't planning on using the bracket, but after seeing it and installing it, I keep my lock on the bracket instead of in my backpack.
In terms of security, the lock is literally just big enough to go around a rack and my rear wheel. It is large enough to be usable with those wavy tube racks and the inverted U racks. But it's small enough so there is very little option for leverage for anybody who wants to steal my bike. The lock comes with 5 keys that are sturdy and small (the plastic part that you clip into your key ring is much skinnier than my previous On Guard keys, which helps to keep my key ring size down).
I don't actually use the OnGuard cable that came with this lock, since I have a Kryptonite one that I was using beforehand. The OnGuard cable is slightly thinner than the Kyrptonite one, but I doubt it's much of a difference since a cable cutter would work through both pretty quickly.
A couple of notes about me... I live in D.C. and commute around the city. I don't leave my bike outside overnight, only during the day.
Just a few days ago I went to check on my bike and noticed that my cable lock had been cut. I didn't ride my bike for a little over a week so I'm unsure of when the person attempted to steal it. Looking at what remained of the cable lock, it appears that it took very little effort to cut it, which is reasonable considering it wasn't meant to be the main theft deterrent. Looking at the u-lock, there appeared to be no damage done to the actual lock or perhaps the thief didn't even attempt to break the lock. However, I noticed that the side of the bike frame where I had connected the u-lock to was partially damaged indicating to me that the thief did put in quite a bit of effort to break this lock.
As for the actual lock, it's fairly small and heavy. You might have a little difficulty locking up your bike as did I at first, but you'll soon figure it out. It's really strong and durable and looks and feels like it can withstand a lot of damage.
Since I now need a new cable, I decided I might as well buy another set of the On Guard Bulldog Mini DT Lock 5015.
That being said, I bought this lock to keep my bike from being stolen, which it did. So, I'd say this lock was well worth the purchase.
There are two slight negatives in my opinion. 1) It's heavy compared to most locks. 2) The U-shaped part of the lock, is surrounded by a rubberized material. This is great so it doesn't scratch surfaces, however, mine started to slide down towards the locking mechanism. So I had to take a razor and shave some of it off.

My brother used this to lock his computer to his desk while at College. It worked just fine, and the added keys are a nice touch!Published 8 months ago by SnapA
The lock works great. It is wide enough to fit around my frame and the thick bike rack without leaving much space for a bike thief to fiddle around with. Read morePublished 11 months ago by B_Mortimus
On Guard Bulldog is a good lock. My bike isn't special, but it cost me about $450 and I would be heartbroken if it was taken. Read morePublished 18 months ago by Lisa
I haven't used this item because it's too heavy and bulky. I couldn't bike around without taking a backpack to carry the lock with me. It may work to some, but not in my case.Published on June 28, 2014 by Rodz
They make bigger locks, but the smaller the better. Not only is it lighter, but most importantly there is less space between the frame and the rack for someone to jam in a lever... Read morePublished on May 13, 2014 by eliphino
3 sets of keys is nice, 1 set has an OK LED light.
