A bull dog mini is not a *** lock. Kryptonite is all marketing. Yes a kryptonite new york will hold up against an angle grinder for 30 secs more, but my second u lock will give it another couple minutes beyond that. A bottom of the line kryptonite is going to be equivalent to a mid to top range bull dog. The bull dog will be slightly cheaper too. If you can show me I am wrong I'll go out and buy some kryptonites and give my bull dogs away on here.

-edit I have a brute mini and pitbull mini with a a cable. Not a bulldog paid about 60 all together
