Amazing Product For A Place With low Crime How Ever if you are Living In The city or hight crime areas I Don't recommend it because the locking mechanism is made of cast zinc with a low melting temperature so you can open this with a lighter if you hold the lighter on long enough but it is a really great bike lock other than that it is really great and had definitely exceeded my expectations For the Price ...
