Review on 🔒 Kryptonite Kryptolok 12mm U-Lock Combo Bike Lock with Side Mount Snap-In Bracket by Rick Rogers

You don't have an emergency key and you tend to get stuck and stuck even if the combination is right. The "sliding latch" is unreliable and can also pop out, preventing you from opening it without serious tools. My wife and I took our bikes downtown for the weekend and this is exactly what happened to us. You're stuck without an emergency key. Locksmiths will not open it without proof of purchase. So it was great home, get tools, great back and luckily I was able to open it with an awl. Kryptonite has other decent products but forget the convenience of a combo (which won't get stuck if you lose the key) when the mechanism is much more likely to jam after 6 months leaving you impossibly stuck. In addition, the U is too small and often does not fit around a bike rack. Buy a U-shaped lock with a long neck and one with a key - stay away from this model.
