Title: It's Still There.
Review: While kind of 'pricey' the thought of losing an item that's costly itself & a necessary form of transportation these days was a huge factor in selection of this security device. As the collapse of society seems more evident every day, the thought of some miscreant 'Coming-Up'... was another motivating factor in investing in a good locking device. This lock is a Beast. It is quite heavy, so those concerned about weight may want to reevaluate choices. In this case, weight wasn't so much an issue. Theft deturent WAS. Cable bike locks can easily be cut with simple cheap cable-cutters quickly. This lock? Not so much. Can it be cut? Yup. Quickly & quietly? Nope. Can it be picked? Yup. Quickly? Nope. Good thick high-test chain was only option. Not liking paint or frame damaged by intense rubbing and/or chain banging, a high-quality sheath was highly motivational in this selection. While the weight can be a drawback, another small issue is the lock cylinder can be a bit finicky at times. However this can be sort reassuring in of itself, by being rather difficult for a novice 'picker' lacking proper tools. Appearance was another deciding factor as it looks tough, rugged & matches bike styling. And... in a 'pinch'...it could make a hellva defensive weapon. 'Peace-of-Mind'... Who can put a price on that? When a beloved 'high-value' item has to be left unattended, it's nice to see that it's... "Right where I left it".

Title: Nice heavy duty lock for my ebike
Review: Its just a heavy duty protected chain lock. It works great while traveling. It has a barrel lock with a round key that seems pretty secure. I would definitely buy again!

Title: Solid bike lock
Review: Needed a solid bike lock for my e-bike. The Kryptonite Keeper 712 is built solid. No lock is foolproof, but I think it would take a bit of work to cut through this one. I like the length of this lock, giving me plenty of slack. They would probably have to use and angle grinder to get through it. The chain and lock have some weight to them adding to the solid feel of the product. So far happy with this purchase.

Title: Bulky but functional
Review: This is a very durable lock. It is very useful when my spouse and I chain our bikes together. It is heavier and somewhat bulky to have along with you on the ride.

Title: Great lock
Review: It was a great lock. Sturdy and durable. It's a little heavy, but you would expect it out of this great of a lock. The fabric doesn't move so it doesn't scratch your bike frame. The only con is the key size. Other than that it's an amazing lock.

Title: Great Quality, wish it was a little longer
Review: Great quality, is perfect to protect my motorcycle. Solid weight and construction. However, I wish it was a little longer to hook around things more easily.

Title: BURLY. Don’t even think about taking my bike!
Review: This chain is the perfect security device for US urban day time locking. It’s the proper length to fit around a small tree, looks intimidating, has a small key hole to prevent picking. Of course you pay a weight penalty, which I think is worth it. I always have paniers on my commuter which makes for easy stowing. Highest praises for this lock.

Review: I am really impressed with the lock. It strikes a great balance between price, weight, and sturdiness. I feel more confident when securing my bike trailer with this lock. I've also heard that this type of lock is more difficult to pick, and I hope that proves to be true. Overall, I highly recommend the Kryptonite Keeper for anyone seeking reliable bike security.
