This thought brings comfort to me.
edit! Great news! My bike was dumped by the thief and found with the lock still attached!
edit 2: Second bike theft, and they used an angle grinder and cut right through the lock. I didn't know you could register for insurance on the company website for $1 so I don't think they will provide me with a new lock, let alone cover the theft.
We considered the Kryptonite Evo Mini-7, but decided on the OnGuard because of the better mount design and superior key system. The key/tumbler on my Kryptonite chain lock (which is the same on the Evo), while effective, is sloppy and takes some jimmying to get it to turn properly. Not a big deal for me, but my wife wouldn't put up with it. Unlike my Kryptonite lock, the OnGuard key/tumbler system is much more precise; the key slides in smoothly and turns without hassle. It even has a built-in automatically retracting cover to keep debris out of the cylinder. I believe it's also there as a pick-deterrent.
I haven't tested the Kryptonite mount system, but there are many reviewer complaints about it being sloppy as well. The mount for the OnGuard lock is adjustable and very sturdy. Getting it mounted in an appropriate location is a bit of a pain due to the small frame size, but I don't think the Kryptonite would have fit at all.
The only problem we have with the lock is that it's only 5.5" long, which makes it difficult to lock a larger diameter frame to anything more than an inch or two away. However, this is precisely what makes it difficult to defeat, as it's pretty much impossible to fit a bottle jack inside the lock. No lock is impervious to theft, but this one sure won't make it easy without a cutoff wheel.
All in all, happy with the purchase.
That being said, the keys are beautiful, just like my Lexus key actually. I had no issues with the locking mechanism, though I also put a drop of dry chain lube in the mechanism just to make sure it stays buttery smooth. I also had no issue operating the shackle.
The U lock is big enough to fit through the back tire and around my seattube, and around a relatively normal sized pole. Failing that, in a pinch, there's the cable lock.
The cable is mostly just a deterrent for those with quick release front wheels but it'd require at least a decent sized cable cutter to get it off.
So - if you're using this to lock your bike up OUTSIDE. Maybe consider something just a bit more heavy duty. But if this is a commuter lock, I don't see any reason to go any more hardcore unless you're locking up in a high crime area. In which case, I'd consider taking your bike inside. I take mine inside 99% of the time, and lock it with this just to be sure someone can't just roll it out the door. Overkill for that purpose, but it's great for those times that I'm in an unfamiliar place and have to leave the bike on the street.
The U-lock fits perfectly between the triangle of the frame, the rear rim, and any bike rack I've placed it on. Just make sure to loop the cable through itself for added length to go through your seat and front tire.
Only ding is weight, this lock is seriously heavy but not a problem when I commute or casually ride.
Please note that these are small and you may need 2. Cough it up, they are worth it. You'll get 4 keys including one light up key.
