3 out of 5 stars.  Mediocre - OnGuard Bulldog STD 5010 Bicycle U-Lock, January 7, 2010
So I bought this lock because it seemed substantial, but after using it for about three months, the key cracked. Apparently the key, being so skinny and long, just doesn't handle the pressure of daily use... can't get to your bike without the key... just something to think about. I like the Kryptonite I used to have much better. The old Kryptonite locks used to be prone to theft because thieves figured out how to pick the locks with the body of a ballpoint pen (thats the model I had... hence the replacement) but the new ones are pretty much foolproof. Either way, they have a killer warranty and I am sure they would honor it (although I have never heard of anybody using a Kryptonite that had to call upon the company for assistance (which probably means what it seems like it means).

4 out of 5 stars.  Great lock - a bit heavy, November 13, 2009
This is a great lock. I haven't had any trouble with the lock jamming.

Two small complaints:

1. My bike has a pretty small frame, so there isn't a place for me to affix the frame holder. This means I either have to carry a bag, or hold the lock while I ride. This isn't a huge deal since I generally carry a bag, but it's a little bit of a pain.

2.It's very heavy

I think this is a good lock for the cost and recommend it.

2 out of 5 stars.  Jammed from the very beginning, May 25, 2009
I wasn't able to open the lock until I found this page of reviews and found out that I had to bang on the lock with my fist with the key turned. Every time I want to open it I have to do this, so I will probably return the lock for a refund.

1 out of 5 stars.  Horrible, May 19, 2009
I bought this in conjunction with a bigger chain lock as security for a moped, came to a total of about 115 dollars. BOTH stopped unlocking, and I ended up having to get a friend with a metal cutter to get my bike off of my front porch. I would not recommend these locks to anyone unless you want your bike stuck!
