Felt like an eternity I waited for this to come in the mail. So worth it!! Actually fit me straight out the packaging. No adjustment needed. But easy to loosen and secure the extra with a band. This lock feels secure!! Wearing it around the waist is easy and weight feels evenly distributed. Took it out next day I got it and didn’t affect my ride at all. The short length I think is perfect for me. I’m only locking one bike and like there’s not much give for thieves to attempt to use their tools. Practice locking/unlocking the bolt. You can take the key out without it being fully locked. So make sure you tug on the handle loop a few times before leaving and to keep the key in while locking then turn to ensure it’s fully locked. Saw some complaints about the weight and it’s really not a big deal. Love that it comes with three key copies.Pro tip: go to the manufacturer website and register your keys right away. Must do it while you have them as that’s the only way to duplicate keys. They need to have a log of the digit code on the keys.
