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.

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.

Great Product That Gets the Job Done!
The Master Lock Cable Lock, 6 ft. (8122D) is an overall great product. The 6-foot cable provides plenty of length to secure bikes or other items, and the set-your-own combination feature is super convenient—no need to worry about losing keys! It feels very sturdy and reliable, giving me peace of mind when I lock up my bike. One thing to note is that it’s a bit bulky, which might make it less convenient to carry around on longer rides. However, the extra thickness also adds to the sense of security. If you're looking for a dependable bike lock that’s easy to use and offers solid protection, this is a great choice!

¡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!

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.

Unreliable/Mechanism failure/Had to cut
I’ve had another higher quality master lock cable from years ago… But this was the only one I could find on Amazon so I purchased it. It’s cheap and cheaply made in my opinion. Barely 6 months into owning this it stopped working with the preset combination for no reason, and I had to manually cut the cable - an hour. For that reason only I’m giving it a low rating (“YOU HAD ONE JOB!” lol). I will go with a higher quality cable for the next one.
