    OnGuard Bulldog STD 5010LM Bicycle U-Lock has been rated 5 starsValue for money
    n

    The feature I love about this lock is that it comes with an LED flashlight on one of it’s key for those times when you’re cycling home at night, and it’s dark, and when you fumble to unlock your bike (cos it’s cold), you just …. can’t… seem to… get…. the key…. in…. arrrghhhh!! but now at least you can see where the hole is and you can insert the key with ease.n

    The lock is also very well designed in that you can’t turn the key unless you’ve got the key all the way in properly. this helps prevent damage to the lock (and to the key) when you try and force the key to turn without inserting it fully. (although on the first day i got it i thought the lock was jammed. turns out i inserted the key at a wrong angle) it also comes with a lock holder for your bike so that you can attach your lock to it when you’re riding too.n

    it’s only rated 2 stars for security, but no one’s ever tried to steal my bike but i think having this lock around makes them not want to try. or maybe because my bike is a cheap piece of junk. definitely much more effective than a cable lock. plus onguard has some kinda insurance thing if your bike gets stolen while it’s locked with this lock, which provides some additional peace of mind i suppose.n

    finally, you get free shipping because it’s a shade over $25. all in all a satisfactory product. 5 stars.

    OnGuard Bulldog STD 5010LM Bicycle U-Lock has been rated 3 starsGood, except for the mounting bracket
    n

    The lock seems fine and functions well, but the mounting bracket isn’t working right. It has a yellow latch that you slide a groove on the lock into to mount it to the bracket, and it is supposed to keep the lock from sliding out again. The yellow latch also has a thumb piece that you can push on to release the lock. But I can pull the lock straight out without even pushing the thumb piece, this would probably be a major pain if you’re riding over bumpy roads and the lock decides to slide out and onto the ground.

    OnGuard Bulldog STD 5010LM Bicycle U-Lock has been rated 2 starsNice Lock, But Key has jammed
    n

    It’s a nice lock. I bought it to replace my Krypto, after the viral video of how to hack the Kryptos. It worked good for about 2 years and has been a solid U lock — but now the key will only turn half way – jams in the middle. I have oiled it and cleaned it – cant fix it.

    OnGuard Bulldog STD 5010LM Bicycle U-Lock has been rated 3 starsDecent Lock
    n

    As they say , “You get what you pay for”. At $25 this is a decent lock that I would use to secure an inexpensive bike. But wouldn’t feel confident that this puppy could protect a quality bike from well-healed criminals.

    OnGuard Bulldog STD 5010LM Bicycle U-Lock has been rated 4 starsAwesome durability, even through foul weather.
    n

    After reading a blog entry reviewing several bike locks, I was convinced that this OnGuard Bulldog u-lock was the one for me during my college days in the Midwest. Through several seasons now, the lock has proved its durability and the extra keys have been really handy. (Just don’t rely on that keylight!) My only concern would be about the lock’s performance in freezing wet weather. A few times, water snuck into the locking mechanism and froze into an annoying problem. Granted, I didn’t keep my bike in covered storage, and the ice wasn’t anything my grip and twisting strength couldn’t overcome with a minute of diligence. I like this lock and I think it got the job done well.
