Pros: works as described, although this was a larger u-lock than i had imagined (compared to the one i already had) Cons: Other thoughts:

Pros: compact and versatile Cons: The key sits funny on my key ring. Kinda bulky there. Though it's weird size makes it an easy key to find on the ring. Other thoughts: I have not tried the frame carrier yet.

Pros: Strong, sturdy haven't used it yet, It appears to being a sufficient solution! Cons: Heavy Other thoughts:

Pros: quick delivery, great price! Beat Walmart and Target. Cons: none Other thoughts:

Pros: Strong, heavy-duty, cable is very useful for securing wheels and other things. Cons: A bit heavy, but that's what you get for something strong that will resist attack. Other thoughts:

Pros: Looks hard to break/cut Cons: heavy Other thoughts:

Pros: able to lock two bikes or two wheels securely. lost keys are replaced for free one time. Cons: lock holder is a little hard to remove lock from. but can be remedied by tweaking by not tightening it to much to bike frame. Other thoughts: I paid a bit more for this lock from a local bike store and thought it to still be a good deal.

Pros: Lock arrived with the very thick flex cable, but I have been using just the U shaped steel part. It is tough, easy to use and easy to secure. So far, every time I left the bike, it was there when I returned! Good news. I did not permanently mount the lock. Instead, it is just locked around the frame upside down. Works just fine that way. Cons: It was virtually impossible to find a place to permanently mount the lock using the included kit. Either it would interfere with cables or would be in the way of the ride. The place I chose to store the lock while riding, on the front of the frame, but far enough back to not be in the way of the front wheel, works, but it's not perfect. Still, it's fine. Great lock. Other thoughts:

Pros: very sturdy, full armored, and anti-theft Cons: little bit heavy to carry. Other thoughts:

Pros: heavy and sturdy construction. almost all metal parts are plastic covered rotating cover that covers key slot so it's not so apparent Cons: nothing that i can see yet Other thoughts: haven't used it yet, but appears to be a pretty good quality unit to give some peace of mind when i lock my bike up when out and about. needs to be registered w $10 within 15 days of purchase in order to qualify for anti-theft feature. nice to have 1 set of keys that can be replaced free if lost.
