Kryptonite Keeper Disc Lock
Great for what I wanted
Lock is solid and is really great that it comes along with the reminder cable. I live in SF and I just need a little extra to make me feel safe about my bike as it was almost stolen before. Although I'm sure the lock could be broken its a bright yellow deterrent that says "hey I'm more work then you want to go through". I'm very happy with the lock and would easily buy another one or recommend it.
That being said I will say that the dusk cover doesn't go in very well and tends to just "flip" out. And although I've only been using it the last month the yellow paint on the inside has already started scraping off. I bought two locks for myself and my girlfriend; to not mix them up I added a strip of red nail polish on one and found that rubbing alcohol will strip the yellow paint off a little.

Good solid lock
This is the first disc lock i've ever bought and am satisfied with it. It is solid and the lock works very smoothly. My favorite feature is the rubber key seal the keeps lock from oxidizing or getting jammed with debris. Foer the price its a great buy. Make sure you get the right size pin because i got a smaller size pin and should have gotten a larger diameter pin.

Simple disc lock
It's a very simple lock. The pin is small and the 'body' is bulky and hard.
I would suggest to always park on 1st gear, lock the bar and use a motorcycle cover.
If you forget about the disc and try to roll out your bike, or worse, actually ride it, you are going to have a damaged disc, if not, a lame fall.
If a thief try to take it, will have to deal with locked bar, finding neutral and braking the lock.
Anyways, it is more a psychological relief than an actual safety device, in my situation.

Good build quality. Protection to portability all in one.
The paint chips off quite easily, I have it stored in the passenger seat compartment and it touched some bare metal. No biggy. It's very tough and feels very solid. I doubt anyone would be able to break this off easily. It's a piece of mind and the fact that it's so small you can bring it quite easily.

Easy to use...period
Super easy to use and cable that comes with has a dual purpose to secure riding apparel just by using the helmet lock under the seat...I love it

great bang for the buck
Everything can be stolen. The bright yellow will help deter thieves from your bike. This will really help slow down any potential threat with its heavy duty constriction. Way more portable and usable than a cable lock.

Does what it says
I put this lock on my bike every time i get off of it. It goes on and comes off very easily and quickly and give me a sense of security when im not watching it. Also, as an added bonus, the yellow of the lock blends very well to the fairings on the bike.

It works. I hook the leash to my rear brake pedal and the lock to the rear wheel brake rotor. The yellow paint seems thin and quickly comes off, but I don't really care. Use the leash! I failed to hook up the leash once, and I started moving the bike, but thankfully it was on flat ground and there was no damage to the bike. I do not know about how easy/difficult it is to defeat, but it is metal not plastic. If I am away from my bike more than 20 minutes, I use this lock, the steering head column lock, and my comprehensive insurance policy. I believe this is the best cost/return ratio you can have.
