Very secure lock seems to be well made.
I did a lot of research on bike locks before buying this one, and I am super satisfied with every aspect of this Kryptonite Evolution Mini Lock.

I bought the Mini U-Lock after using many different locks including a high end Kyrpotonite NYC chain lock. While the chain may offer more protection having a lock that weighs half as much as my bike, and requires a bag to carry it simply is not practical. The Kryptonite Evolution-Mini U-Lock, fits easily in my back jean pocket.

90% of the time, when riding in NYC I need a lock to keep my bike safe while I stop at a restaurant to have a cup of coffee or a meal. Usually I can even see my bike, so I need something strong and light. I ride a fixie so I use the U-Lock with a cable through the front wheel. Total weight is very small.

Would I trust the Kryptonite Evolution-Mini U-Lock to leave my bike while I went to a movie? Depends on the bike and where it is locked. I have done it. The Mini is not easy to get off, but of course it can be more easily attacked than the Kryptonite New York locks. But all the tests I have read show it is not an easy lock to remove because it is so small the there is no "bite" for tools. As far as the keys, same as it bigger brothers.

I really like the lock.

I downgraded to this lock from New York Fahgettaboutit Mini (NYF). The inside diameter is about the same size only slightly smaller, but less than half the weight!

Main reason for this choice of U Lock was for weight savings, mounting bracket, color, and small size. (it truly does fit anywhere)

Weight is almost not an issue no matter how you carry. Backpack, back Pocket, or Bracket are not a problem. The crushing weight of the NYF was unbearable. So hands down this is far nicer to ride around in.

I've read many reviews on how hard it is to get the lock out of the supplied bracket. I've been using this ulock daily in the bracket for 2 months. I have it mounted to my seat tube, and yet to experience a problem. It's been mounted so that I have about 3 inches of clearance from the top tube. When lifting the lock upwards it will gently bump into the top tube letting me quickly know the lock is free and ready to be removed. I've never pinched my fingers as some have claimed, or had to wrestle with the release of the bracket EVER. Maybe I got a newer designed bracket? Or maybe I'm not retarded and can use a ulock bracket correctly? The bracket is the main reason I got rid of my NYF (to large to have a bracket) and I LOVE IT, works as intended.

I hate to admit it but one of the most compelling reasons that I got this lock over the much cheaper and nearly identical ulock (series 2) was the bright orange color. I just love it, and it's been easier to spot my bike on the rack.

Using a commuter bike doesn't lend itself to being easily locked up by this ulock. But I knew that after using the NYF for a year. There are a few times I've had to be very creative on what I've locked the bike up to.

The Evolution Mini is definitely a great lock. It's small, well built and is one of the highest rated bike locks on the market. It weighs about 2 lbs which isn't bad considering it's high rating of protection. The Evolution Mini can fit in your back pocket but be weary of the "E-Z Mounting Bracket". It's cheap and of questionable quality. Don't be surprised if the mounting bracket snaps in two or swings around when you hit a bump. (I don't use the mounting bracket because it's so crappy.)

I like the fact that the Evolution Mini won't let you take the key out without it being properly locked. This feature is actually invaluable. You know for a fact that the lock is indeed locked tight the second you pull out the key. No second guessing or having to tug on the lock to make sure it's fully secured. Very nice.

Note: The keyhole can be a bit finicky if you don't insert the key all the way and properly. Just take your time and don't force it or you might break off the key.

The Evolution Mini is smaller than the average U-lock. This is an advantage in that the less space left open, the harder it is to use the empty space for cutting tools and leverage attacks. The only downside is that you can only fit your bike frame and one wheel when securing the bike to a bike rack/object. This leaves the other wheel vulnerable to theft if you don't take further precautions like using a bolt or pit lock instead of a quick release for that unlocked wheel or using a second lock or a cable. Oh, and in some situations, your options to lock the bike up might be limited due to the Mini's small size.

Another feature I like is the sliding keyhole cover.

The Evolution Mini is a good buy for the price. It it solid enough to provide ample security without the dead weight of the New York Lock. The quality control seems to vary on the keying mechanism, and it is sometimes difficult to engage the unlock mechanism. I've used another copy of this lock, which didn't have the same issue.

I have also found out some information that is relevant to those who are interested in having multiple Kryptonite locks that are keyed alike. After purchasing this lock, and contacting Kryptonite to purchase a second lock keyed alike with my key-code, I was told that this can only be done if you purchase the locks together. You cannot order additional locks keyed alike to existing purchases.

To buy these locks or other Evolution locks keyed alike, you must purchase them directly from Kryptonite. Unfortunately they charge full retail, which is up to 50% more than what Amazon charges, with an additional $5 fee per EACH keyed alike lock. Not a very good deal for a mild convenience.
