5.0 out of 5 stars Big, but I feel more safe/assured now., December 12, 2009

This is big. And heavy. But definitely worth it. The long length is nice for awkward placement when looking to sturdy objects--long reach. The key action is smooth for locking and unlocking is smooth. There is a little key hole cover that can keep the area relatively clean and free of debris--- although I haven't left my bike and lock outside for a whole Seattle winter/spring season and I don't plan to do so.

I specifially purchased this lock for the insurance. Be sure to read the instructions on the box of the lock. This is where all the info is. Kryptonite has very vague information on their website about this which I believe they do for their own advantage. Basically their are several hoops to jump through to both register a bicycle and to file a claim. I suggest contacting Kryptonite directly if you have any questions. They quickly responded to my questions in about 1-2 days, as well as follow up questions.

Here are the basics to understand about their policy(again, you should confirm this with Kryptonite):
1) completed the Anti-theft Registration form that's included in the lock's instructions (this includes the lock key registration number)
2) the Kryptonite lock bill of sale (mine was a copy of the Amazon invoice/receipt)
3) an authorized bike shop receipt or appraisal for declared current value only--does not include accessories or tax
4) proof of bicycle registration with local authority (police,campus,etc)
5) and a check for $10 (2 years of coverage) or $15 (3 years). The 1st year is FREE. No more coverage after 3 years

NOTE: NY residents have a different policy/requirements: contact Kryptonite

For filing a claim, I don't know-- haven't been in that situation. I know you have to send Kryptonite the remnants of the failed lock. Probably a police report, too. I would personally add a bottle of my own tears.

Back to the lock-- yes, I recommend it to any friend. And don't leave your bike unattened without it. Unfortunately, if someone really wants to steal your bike and they have the equipmet to do so, you are SOL. Just be smart about where an when you lock your bike. This lock provides a little piece of mind.

I've been using this lock for a month now and my bike is always where I left it. I feel secure leaving it on the street for hours at night, and it's really great that it's so big, so I can lock two bikes together with no problem. The keys have stuck a couple times, but it's not really an issue.

5.0 out of 5 stars Solid lock, December 25, 2009

There is no doubt that this is a solid lock. It weighs as much as an anchor, and with its dual-locking mechanism it is pretty much impossible to break open (though it has been done with those air guns that are used to kill cattle in slaughter houses). It has rubber all around on the outside and a dust-cover for the key hole. Basically, if you are familiar with Kryptonite lock construction this is pretty much like all the others.

It comes with a key that has a little LED in it, making it easy to unlock this at night, though it is rather bulky to keep around in one's pocket.

This lock will stop any thief in their tracks, but for something that is this heavy, you might as well purchase one of Kryptonite's New York locks, which are much more solid in construction (if that's possible), as is evidenced by Kryptonite's increased insurance policy for those locks. If you are on the fence between this one and a New York lock, price and features should be the only factor, because both Series 4 locks are the same size locks in the New York line are pretty much the same weight.
