Kryptonite Keeper Disc Lock 4.7 5 40 40
Good front break disc lock. Looks is small and not too heavy. Easy to carry on a backpack or a saddle bag. November 23, 2015
Great lock! Be careful where you throw it... I bought this lock to keep my bike safe when I go to the gym.. Since I park my bike outside during gym hours.. This lock felt very sturdy and gave me peace of mind. They provide two keys which is great since I have a tendency to lose them often. The yellow is perfect. Its easily visible at night and it helps to deter thieves. On a random side note. I was playing around with this thing in my room.. Sort of juggling it back in forth between my hands. I accidentally mistimed my toss and catch and it flew right into my kitchen cabinet and smashed right through the wood... So please be careful with this lock! its quite hefty. Otherwise i give this lock a A++. Great buy! Thanks revzilla November 16, 2015
Good Lock I bought this lock after reading the potential problems with alarm systems. I did not want to be bothered with the alarm going off by accident at night. This one does the job fine. Aside from it being a strong lock, getting it in yellow lets people know you have a lock. November 6, 2015
Well Worth Investment Lock is very smooth in its operation and is very easy to see which deters potential thieves. Love the remove before flight cord - I put it onto the throttle and this ensures I do not have any "accidents". October 26, 2015
great lock on a budget bought this lock because 1, i'm kinda broke and needed some kind of theft prevention. 2, kryptonite has a great rep. i've owned a different disc lock before and it was great. however, i now have a different bike, with a different style front rotor, so my old lock wouldn't fit. this one fits, and works well (as in the bike hasn't been stolen). it's a little tricky trying to get the pin through the holes in my rotor, but nothing so bad that i'd knock it down a star. just gotta have a little patience. the rubber flap to plug the key hole is a nice touch. so far has kept out any water and dirt. before buying, i highly suggest you measure your rotor thickness, and the diameter of the holes drilled. this guy just fits the thickness of my rotor. any thicker and it wouldn't be able to slide on.

Great low-cost disc lock Kryptonite makes quality products and this is one of them. While this may be on the bottom of their "food chain" (I must be watching too many of Revzilla's videos. I'm starting to talk like Anthony) it is by no means a slouch. At very affordable price, the value of this not-so-little lock is hard to beat. The lock itself is incredibly dense and heavy. So much so that it is uncomfortable to store it in any of my jacket pockets. Additionally, the profile of the lock makes it basically impossible to fit a pair of regular bolt cutters over anything essential (I can't speak to the super heavy-duty fire fighter bolt cutters as I don't have one). I carry my lock under my seat everywhere I go and the little extra piece of mind that it provides goes a long way. I wouldn't buy this to keep a Ducati safe, but for my purposes it does the job just fine. October 5, 2015
No complaints! Super light, cool color, easy to use, and does its job! September 28, 2015
Works so far! I park in downtown Philly most days when I commute to work. I always have the lock in my side cases, however it would certainly fit in your pocket if you were tight on space. So far, the lock hasn't face the ultimate test since everytime I come back, my bike hasn't been stolen yet. Nonetheless, the lock is well made and works as a good deterrent. I also appreciate that the key is rather compact, so it doesn't take up much room on my key ring. September 28, 2015
