Review on Pacsafe Retractasafe 250 Lock: High-Tensile Retractable Cable Safe For All Genders by Jake Hillyer

I use it to lock my bike saddle to my cable lock when securing my bike at work. Granted, this would be woefully insufficient in a high-crime area; but it suits my needs just fine. While it wouldn't deter an experienced bike thief, it does provide enough frustration for someone looking to steal a bike saddle as a crime of opportunity to serve as a reasonable deterrent. Works well, and is as secure as expected, given its size. I love that I can just stash it in the little under-saddle bag on my bike.
