    • It was amazing. Will buy this one every time
Great thick cord that travels very well. It balls itself back up you slide it into the carrier and you are ready to roll. I can’t stress this enough it was SUPER easy to set your combination and Super helpful. This thing has great length. It’s durable, it looks amazing. Its size is perfect for bikes and the latch has absolutely amazing quality. I suggest this lock to anyone for this price it’s one of the best out there. ... show more

    • This is the cheapest you should go, but it works well enough.
We bought a few of these for our bikes and stroller in a parking garage. I dont think this would stop a determined thief, but its hearty enough than someone else usually has a weaker lock next to you. I like that I can change the combination, sometimes I loan my bike to a friend so I will change the combo for them so I dont give up the code I had been using at the time, and can constantly keep changing as you go. It's coil is a bit to taught, which makes installing it uncomfortable and annoying, but it is long enough to secure any bicycle and easy enough to unlock. ... show more

    • Worked for what i needed
This lock was bought to keep a gate locked at a new home construction site. It was easy to set up the code, and the lock is easy to use, as I don't have to worry about hiding a key or giving out multiple keys for all the different contractors coming onto the property. Seems to be well built. It's a little long for what I needed for a gate, but I could probably reuse this somewhere else once the building project is done. ... show more

    • Too easy to change combo
This lock is strong and a solid choice, but it is too easy to change the combo. My kid rode to school, had some issues locking up his bike, and a friend accidentally changed the combo. I took me about 30 minutes to figure out this new combo that afternoon. For an adult, 5 stars all the way. For a kid... it depends. The mounting system also did not work for kids bikes due to their size. Worked fine on a 26in adult bike. Recommend this lock, great brand, but be mindful of youth applications. ... show more

    • Can’t Be Easily Cut
Unfortunately it’s a really good lock as it’s not easily cut. Would be very difficult to steal anything it locks up… However when it fails to open that’s not helpful! Bought this for my daughter to use while in Atlanta. Right away, we changed the code so she would be able to remember one she established. You attest the side dial and set the new code. We did that and tested the new code several times before locking up her bike. The next day I put the lock together and locked up her bike. She was able to unlock it herself and rode to a local Target. When she arrived, she called me and asked if I had difficulty putting the lock back together when I used it, I said no, although it was a bit “stiff”. I told her to push it together and that should be fine. She did eventually, locked the bike, and went into the store. When she came out, she could not open the lock. She tried several times and it would not unlock despite having unlocked for me, and for her. She asked for help, tried lubricating it (since it was stiff), and nothing would work. The lock would not open. She asked for help from Target employees and security. Even though they could not get it open. They tried cutting it with typical bolt cutters and it could not be cut. It took a locksmith to open it and they used specialized cutting tools. So while this is a great lock that is not easily cut, I am having a hard time giving it more than one star because she used it three times before it wouldn’t open. It’s being returned. ... show more

    • Amazingly strong!
Use: Lock kayak dolly to trees/rails near launches. This sucker is STRONG!!! It's not like the cheesy locks you see at the Walmart or Target. It is very thick, and the length is plenty to go around just about any tree. It literally took 30 seconds to program the release code, and it would take another 30 seconds if I wanted to change the code. I also tested it against the slip of paper challenge that's circulating on social media, and it did not work on this lock!!! It is well built, long, and strong! Best lock out there if you ask me! ... show more
