Review title: Lock jammed after a month and a half
Product review: I bought the onguard U lock after a thief cut my cable lock and made off with my brand new bike. It is heavy, but easy to use. I was very happy with it for a month and a half until one day I tried to unlock it and it no longer worked. Key only goes in half way. Luckily it was not on my bike at the time.
