Kryptonite Keeper Disc Lock 4.6 5 35 35
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
Small and works well It is good quality and It does what it needs to do. The size is small which is a plus, which allows me to store it under my seat. I love the reminder chord; it could prevent a big headache. September 18, 2015
Simple, yet effective lock If you're looking for a Disc Lock but don't need all the bells and whistles; simply a lock that does it's job, this is it. It's very easy to use and setup. The key cannot be removed unless the lock is properly fastened, so you'll never need to worry about it being properly locked. If the key came out, it is. September 14, 2015
Basic but effective disc lock. For a less-expensive option, this lock works well and has a nice clean design. Locking mechanism is smoother and easier than other Kryptonite products I've had before (no issues with key not inserting all the way). Also, the combination of the neon yellow lock and neon orange reminder cord provide a very obvious visual that bike is locked. Only complaint is that because of the stiff, plastic material used the reminder cord is kind of bulky for throwing it in a pocket. I use this for parking on the street in Brooklyn during the day because it's light and easy to carry, but use a Kryptonite New York Noose overnight. September 14, 2015
Small and portable A step towards fending off theft. Its small and portable. Sometimes I have to jiggle the key to get it to release. Comes with reminder cord. I accidentally bought another because it didn't say it came with one in the description. No use in returning it though. September 3, 2015
excellent these little locks seemed durable and strong. the most fantastic this is they fix in my kawasaki ninja 300 storage department August 3, 2015
