I left my bike locked overnight at school because I couldn't take it home with me that day. When I came back for it the following morning it was torn to pieces but everything this lock was attached to stood its ground. Now I have a frame and a broken wheel of what was once my only mode of transportation besides my feet but hey, the lock did its job.
OnGuard sells many locks, and the Bulldog LS is probably the best bargain quality lock they sell. LS stands for long shackle, which is nearly 12 inches. There standard model (STD) is about 9 inches, and their mini is around 5 inches. The smaller the shackle length, generally the safe the lock as a thief won't be able to pry it open. However, unless you have a perfect place to park every day, you need the extra length of the long shackle to span the gap.
At around $25, this is a 13mm lock that is impervious to nearly all bolt cutters, and will need a grinder to break into. It is double bolted, meaning, a thief will need to cut in 2 places to get to your bike. Odds are, that will cause too much noise and they will get caught.
The kit includes 5 keys (seems a bit excessive), the lock, and a mounting bracket. Some people complain about the bracket, but I've got it set up on 3 different bikes and never had one fail on me. I think it just depends on how you secure the heavy lock. If the lock is at a weird angle and putting a lot of pressure on the bracket, it will break. Use common sense here. You can also just use a rear rack to hold your lock instead.
Dollar for protection, this is a good deal. If you want something safer, the Abus locks tend to be the next step, but are 5x the price. You are likely better off with 2 of these locks than 1 Abus. Make sure you lock your bike correctly (not just through a wheel, or just through the frame). People can leave the lock with part of your bike there, and steal other things (like a wheel, seat, lights, computer, etc).

I bought the On Guard to replace the Kryptonite. When locking and unlocking the kryptonite lock it gets stuck halfway and requires jiggling to get it to go. I'm seriously concerned that I may be somewhere and unable to unlock the bike.
The kryptonite is much heavier and feels sturdier. The OG is lighter but still feels well made.
The big problem with the OG is the mount onto the bike. The mount is flimsy and slides around even when I tighten the screws hard. As pointed out by other reviewers, it is very difficult to get the lock to snap into the frame. In messing around getting the lock into the mount, of course the mount moves.
Despite being heavier, the mount for the kryptonite is much more stable and very easy to click the lock in and out of.
I would not recommend this lock for most people bicycle needs. The reason is simple: it's too big. One of the most common types of bike thefts is via leverage attack, meaning they use the bike itself to leverage and break the lock. This lock is huge and therefore particularly vulnerable to this type of attack. Possibly if you plan on removing your front tire and locking it alongside your rear tire this lock is for you, but even then I think it's larger than you need. The mounting mechanism appears to be good, but I've hardly used it because the lock is too big to reasonably mount anywhere on my bike.
Consensus: OnGuard is a great brand and I totally recommend getting a lock from them. Check out OnGuard Bulldog Mini U-Lock (Black, 3.55 x 5.52-Inch) for one that's better for a normal bike owner. I'll probably be selling mine and getting that one soon.
