Secure
Product feels strong and good quality, so it feels trustful to leave your personal belongings attached to it. Very friendly to use and switching codes it’s easy, which makes it easy to open, never had an issue of it getting stuck. Black color makes it disguise very good. Length is fine, gives you around enough length to attack your bike for example to a post and make it feel secure. I def recommended it’s for its good quality and not expensive as other options.

¡Mucho bueno! Me gusto.
My bikes have been vandalized - but not the part that was locked! I could see where the vandal had tried to cut through the cable, but they failed. Ha ha! So sad for you! I trust Master locks - always have. Now I've got two of these, which means I can lock both wheels to prevent another theft. Go away, thieves! You can't defeat the Master!

Feels solid easy to set/change your combination
This lock works really well. It’s long enough to lock around the frame and tires. I love that it has a place to mount it on a bike frame, and easy to mount. It feels very secure. Well designed looks sleek but sturdy.

Good theft deterrence
The lock works good and it’s awesome to have it attached to the bike while you ride it around. It’s so held up good in the rain and elements without rusting or getting stiff. This will deter most would be thieves. It is still a cable lock and would only take >1 second to cut with a pair of bolt cutters or an angle grinder so it may not be ideal for all scenarios like locking a bike outside unattended for extended periods of time in a back alley.

Size and quality
It has the cable neck holder that you can store the cable on your bikes neck under the handle bars out of the way and set your personal combo like lock combination.

Pros: reputable company, sturdy and durable cable. Cons: it’s heavy, the lock part is glitchy, it gets stuck and hard to pull apart, apparently real easy to reset the combination without knowing it. When this happens you have to jump through all kinds of hoops to get help from the company. Emails, 7 days to respond, affidavits with all kinds of documentation (which is understandable unless you are out of town and the bike is locked and you have to get the bike released asap). The cables can be cut through with some effort. Will not be replacing with this company. Apparently this is a known flaw to them.

I had my bike locked using this product and someone was able to cut through and steal the bike. I wouldn't recommend this product. My bike was at a train station so the perpetrator would have to be relatively quick. I'll have to go with another option maybe a chain.

Don't why it has to be this long, but it coils up nicely, and it's easy to hang anywhere on the bike. Nice tumbler lock. Dam tough.
