5.0 out of 5 stars Value for money, February 8, 2008

By	Wi Kwong Yong (Austin, TX USA) - See all my reviews (REAL NAME)

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.

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.

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.

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

2.0 out of 5 stars Nice Lock, But Key has jammed, July 6, 2008

By	Robert Cannon "Cybertelecom" (Arlington, VA United States) - See all my reviews (REAL NAME)

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.

4.0 out of 5 stars sturdy and reliable, December 24, 2008

By	David (Los Angeles, CA USA) - See all my reviews

I have bought this lock twice. First of all I live in LA so bikes don't last very long even with a good lock. The last bike I had got stolen 1 hr after I had left it locked. I locked it with this lock but didn't lock it to my apt fence (i put the bike inside) because I thought "cmon I'm only going in for an hour and coming out right away so why bother with the hassle, its not like I'm not locking it" and surprise surprise, little did I know that bike thieves would just lift my bike (it was a pretty light road bike >=[) and walk out the apt gate. I don't really blame the lock but it is something to consider.

Ok. sorry back to the review. The lenght of the lock is ok. And it is a definite plus that it comes with 5 keys!!! one of them having a led light. the lock barrel turns so that you can cover the keyhole from dust and water. However, the locking mechanism is sometimes a bit heavy and doesn't turn that smoothly but it is definitely not a problem.
