 Good basic lock with distinct pros and cons.Aug 14, 2007
By T. Shih
This lock is pretty robust and has a solid locking mechanism. It's definitely a step above the previous Kryptolok STD which sells for the same price. (UPDATE NOTE: Kryponite has since updated the Kryptolok with the release of "Series 2". My comments reflect the original Krypolock only.)
Onguard comes with a bunch of keys (at least 4 spares + 1 LED key) and has a good locking system. (The Onguard is a double-lock where both ends of the U are secured by bolts) In addition, the lock cylinder of the Onguard lock is technically superior to the old Kryptolock's - not only is it deeper but each of the discs that comprise the locking mechanism can independently rotate, which makes the lock very drill resistant). Finally, the Onguard crossbar seems better protected than the kryptonite's - there's a bulky and relatively thick plastic housing that surrounds it.
The Onguard Bulldog comes with a rather limited but free 1-year protection plan in case your bike is stolen while being protected by select Onguard locks. (The kryptolock has a different protection plan.) The Onguard plan offers up to ~$1251 to replace your baseline bike (doesn't cover accessories or parts you added beyond the baseline) and is valid anywhere besides New York. The key limitation in the plan is that it only applies to locks busted by hand tools AND you must return the broken lock back to Onguard. Keep in mind that only the chain and u-locks have the protection plan.
I've never found a mounting system that I've liked so far, and the onguard lock-mount is no exception. The mounting ring on the U can freely rotate so even if you can position the lock perfectly, it can still swing about. Also, I've found that the lock mount mechanism is a quite tight so you'll really need to struggle with it to get it to work - Personally, I just throw my lock into my basket Topeak MTX Rear Bicycle Basket.
After about a year of ownership in Berkeley, I'll have to say the lock isn't super durable. The plastic end-caps on the crossbar section no longer stay on if the U isn't inserted - but this is merely cosmetic damage as it doesn't really affect the security of the lock.
In the end, it's a great lock for the money.

 Prone to jammingApr 21, 2007
By R. Stanchak
I got this lock because of the price and recommendation in online forums [...]. On first impression, it was a bit heavier than my old kryptonite (circa 1997), though presumably more secure. The mounting hardware is certainly more robust (my kryptonite occasionally 'jumped' out on bumpy roads).
It has now been three months using the lock in Wash. DC, and yesterday, I could have said I was perfectly happy with it. However, today, it wouldn't unlock. The key turned and everything, but the mechanism would not release the lock! After awkwardly struggling with the locked bike in front of Starbuck's outdoor seating for around 15min. I gave up.
Later I came upon some advice at Onguard's website:
[...]
Basically, one needs to 'tap' the lock while turning the key to jar the mechanism to release. After 10 minutes of tapping with a hammer, I started 'hitting', and eventually that did the trick. In some experimentation, it appears that turning the key very quickly is also effective.
I plan to keep the lock for now, but if this happens again, it is going back to the manufacturer.

Jammed LockApr 17, 2008
By Han Jung Hsu
I've had this lock for a day now and the lock was jammed already. I locked this bike to a sign post and I couldn't unlock it afterwards. It took me well over 40 minutes to no avail so I went online to see how to get this thing opened. The other post that told said to "tap" on the key barrel is true, however, it's more like you have to hit it REALLY hard. If this ever happens to you, don't try to pull the lock because that won't work.
Other than that, this lock is super strong. I almost had to cut off the sign post to get my bike back!!

Prone to jammingFeb 02, 2009
By The A Team
I've had this lock for about half a year now. I live in Minnesota and every once and awhile the lock would jam for about 5 minutes while I fumbled with it. I mention MN because it can get extremely cold and fumbling with a bike lock is not the most ideal use of time. Today the lock jammed up much worse and I've spent more than an hour and a half attempting to unlock it to no avail. All I can find in terms of how to fix it is to bang it with a hammer (which I can assure you fixes nothing). So while this product is durable and cheap, use with caution. You may end up with you bike stuck around a sturdy metal pole.
