Bests & Worsts Reviews from Amazon

WATCH OUT!!!!! If you buy this lock on AMAZON, you CANNOT register it for the ANTI-THEFT PROTECTION OFFER (ATPO) service through Kryptonite's website. I bought this lock that is listed as being the "Kryptonite-New-U Kyptolok series 2 standard bicycle U Lock with 4ft Flex Bike Cable"; however, the prefix letter on the key is a "P" indicating this was not a series 2!!! Unfortunately, you need an itemized receipt when registering your lock on the website for ATPO, and since the lock does not match the key type you are unable to register the lock with the same name that is on your itemized receipt. For security purposes, many people have had experiences where their locks have been broken, so to me it was top priority to register the lock for this anti-theft program. On top of this, the key and the lock do not match up easily. It takes jiggling the key into the hole for about 15-20 seconds and I've had the lock for less than a week. One of my family members bought a Kryptonite lock about 4 years ago, and they experience similar issues. I thought their experience was just normal wear and tear through out the years, and that if this was a flaw with the lock, then it would have been fixed for the newer models. I was wrong. I 100% DO NOT recommend buying a lock from Kryptonite!
