Why take our word for it? Look at the company's standing on testing sites:

PS: i have an onguard bulldog for my mtb beater. Strong heavy lock that tested really well and was dead cheap. For new bike, expensive to me, I have a Kryptonite New York which was cheap enough form amazon.co.uk I felt (local prices suck ~ €100). I think both are good, comparable locks although one was twice the price. But the Kryptonite has that yellow which just screams feck off!
