Review on 🔒 Black Kryptonite Keeper 712 7mm Chain Combo Bike Lock by Sal Muniz

I feel bad about this. I know this is one of the strongest bike locks you can buy, but when you watch YouTube videos of someone using a battery-powered grinder to cut through this chain in just a few seconds, you're wondering if you're using something that heavy and need durable. If it takes another 10 seconds to cut it through, I don't think it will deter a professional thief at all, but I think the guys with bolt cutters are going to have a hard time getting through, so it has its perks. Very heavy to wear and therefore difficult to give a better rating.
