bike lock

I wanted to check out this bike lock. I often ride my bike around town. My brother had his bike stolen last year he had a extra thick cable lock I am guessing they cut it open with a bolt cutters. So when I lock up my bike now I try to put it in a high traffic area. I like this lock because it has the solid U shape bar. I have heard these are the hardest to cut through. The one thing I notices is that the locking part of the bar is hollow which seems a little weak to me but I am thinking there is not an easy way to cut it open with bolt cutters. I was able to check this out for a discount in exchange for a review. I have used it and I like it. It is heavy duty and would deter most bike thefts would recommend it #SafeBestBikeLock
