A good compromise between convenience and security
“I didn’t read the instructions before throwing it in my saddle bag and heading out to work. then realized I had to set a combination and had no idea how to do it. 10 seconds later I had it figured out and done. very easy to use and set combo.
Durability wise, I’d say this is more of a “please don’t steal my helmet” polite request than any kind of real security…but if you need real security I’d hope you wouldn’t be leaving an expensive helmet on the bike anyway as a prepared thief won’t be deterred by most locks you’d actually carry with you anyway. This is a solid combination of compact, easy to carry and use, and moderate level of security. I’m pretty sure I could break it in a few seconds with a couple of channel lock pliers, but I’m equally sure I coudln’t breakit with my bare hands. “
