Great lock, highly recommended!
Eventide
While resignedly trying to put it on this way, I noticed that the bolt would not hold the front of the bracket to the back.

Sometimes the key is sticky, but it has never been stuck completely.

I've been using this lock for about two years now, with no problems. When I am not riding my bike, I actually use this to lock the steering wheel on an old GM truck I own that is notoriously easy to steal.

However, I would suggest you NOT use WD-40, as WD-40 is not technically a lubricant - it is a SOLVENT which is more of a water repellant and rust/dirt cleaner, designed to clean metal parts but NOT provide long term lubrication. In fact, after time, it will ATTRACT more dirt, causing problems for your lock.

Instead, use a spray can of white-lithium grease. White lithium grease IS a lubricant AND is water repellant AND is long lasting, and will work much better in your lock mechanism.

I've had this lock for about a year. I have not had any problems with its primary function. Sometimes the key is sticky, but it has never been stuck completely. I am compelled to leave a review because I believe that the frame attachment harness is unsafe. It is designed to rotate based on the position on the bike, so it consists of two plastic pieces held together by a metal screw. My ongoing suspicion of the durability of this equipment was validated today when it separated from the bike, fell between the petal cranks, and caused me to experience my first over-the-handle-bars wipe out due to the locked up pedals. One bent back tire, broken spoke, road rash, and sprained wrist later and I will be purchasing a larger cargo bag in which to carry this lock. I feel lucky that this did not happen in traffic, as it could have been much more serious. If you purchase this lock and choose to use the harness, PLEASE make sure to check the screw every time you use it. It had obviously been too long since I had checked mine.

UPDATE - 4/15/2014
Was reminded to update this review. After several messages with OnGuard customer services, all communication abruptly went dark and I have not heard from them in the past year. I do hope that this occurrence made it back to the design team to prevent future injury.

This lock is just as good as Kryptonite u-locks. The lower price makes it a better value.

Positives:
-The U is made of thick steel, which I'm confident can not be broken without power tools.
-The keyhole is bump-proof, and very difficult to pick.
-Comes with five keys, one of which has a flashlight on it.
-Comes with a bike frame mount, which can be adjusted to any angle.

Negatives:
-Because of the way it is designed to be bump-proof, the lock comes with instructions to occasionally lubricate the keyhole with WD-40. Not receiving the lock properly lubricated straight out of the packaging is probably why some people have reported their locks freezing up soon after they buy them. I suggest that everyone who buys one of these squirt some WD-40 into the keyhole before they attempt using their lock for the first time.
-The anti-theft warranty must be paid for with a yearly subscription, and it will not cover any theft during which the thief uses power tools to break the lock. I'm quite confident from the feel of this lock that it could ONLY be broken using power tools, which makes the warranty just about useless.

I like this lock a lot. I had an old model that had some issues with the cylinder and while I was waiting for the company to send me a replacement, I ordered this one and have been really pleased with it. I especially like that the cable is fairly long and that the loops in the cable are big enough where one loop can pass through the other, making it easier to use the lock in varied situations.

Great quality lock for the price. After doing A LOT of research I basically decided that at the end of the day, all locks are deterrents. Any lock will be cut if a thief has power tools. The reason I decided to not get something equivalent like the Kryptonite 2 series lock is the whole shared key issue. Everyone has kryptonite locks so if there is a key issue, chances are, you are going to run into someone with the same lock key at some point.

Even with that said, I decided to pair this lock with a kryptonite integrated chain lock and I am very happy with this decision. The Onguard bulldog is A LOT beefier than it looks like in pics and feels very good. The mount works very well and the cable is quite thick. So thick in fact that i have trouble fishing the cable into my saddle. The reason i gave this 4 stars instead of 5 is because you do have to be careful when locking the barrel as it doesn't latch on one side so theres nothing holding it in place until you actually lock it.

I would recommend this to anyone but be patient with the locking mechanism and you should be fine!

This works for what I bought it for, sometimes the key gets sticky when unlocking, but maybe its just user error. :-)

I bought this for my wife's bike, and it mounts alright, and seems nice and solid, but I wish for her sake that it was a little less bright yellow. It detracts from the look of her bike.
