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.

The lock was cut and bike stolen
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.

Pretty dam tough
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.
