bike stolen (2009-04-19)
i suppose i should be greatful that it didn't get stolen sooner, but judging from the marks left on the only remaining part of my bike, this u-lock, it looked like it was pretty easy to pop open. next time i will spend the extra money to buy a heavier duty lock.

Same complaint as others - used this lock and my bike was stolen. (2009-01-31)
Several others have said it, but it bears repeating. This lock cannot be trusted to protect your bike.

I locked my bike just outside my door. Left for work and the bike was there. Came home from work and the bike was gone. Only had the bike for a few weeks. I learned my lesson.

I'll be getting a much tougher lock (actually locks - at least two different ones) for my next bike.

This lock does the job. It is a good U-Lock so thieves can not cut through it. However it is cheap. On one night with rain and then a freeze the lock had ice in it and the key would not turn. I had to twist the key for 10 minutes to get it to work. Not good for use in cold weather but if you want a cheap U-Lock this is a great buy.

Cheap but no durable. (2008-11-23)
It rusts easily and the plastic cover is so loose that it often cover the key hole.

Recommend more expensive lock if you have more budget.

Do yourself a favor and buy something else (2008-10-18)
I'm on Amazon to return this product right now. The key is very fickle -- I can only get the darn thing unlocked 1 out of 20 turns of the key. There might be a trick to it, but I don't know what it is. Also, as far as I can tell from reviews (that I should have read), these things do not keep your bike safe!
