Review on DadyMart Heavy Duty 16mm Bike U-Lock with Combination, Anti Theft Bicycle U-Lock for Road, Mountain, Electric, and Folding Bikes (Bracket Not Included) by Chris Webb

I bought this lock because my previous bike lock was made of plastic and it didn't survive the theft. I knew from research that a metal U-lock would probably be my best bet. When this lock arrived I was surprised at how heavy it is. In other words, it's difficult to pick like my previous lock. I also like that you can customize your unlock code. I don't have any real faults with the lock other than the number scrolling could be a bit smoother but overall it's a very secure lock and I'm sure it will deter any thief.
