I bought it in store, so I was able to choose from a variety. This one look very solid. 1st issue that I had is that the 5-5-5-5 combination in the manual didn't open the lock - sad... Then I started to rotate disks and realized that I can figure out the combination myself - and I unlocked it. I asked my wife to configure it with a different combination - she did - I unlocked it again in less than 15 seconds!! DO NOT BUY, unless you want to donate your bike/etc. to somebody "in need". I'm going to return and buy the one with a key and most likely not Kryptonite brand.
