It should be very popular with thieves....
gizmowiz: Which? There are twelve things. I've heard thieves absolutely love heated insoles and superthermos.
4 directions and 12 presses is 16,777,216 possible combinations, NOT over 22 million. Still, considering typical rotary locks are 40x40x40 for 64,000 combinations it's still an improvement.
I just wish they would drop the charade of numbers and letters, you aren't fooling anyone.
@xionanx add to that combinations where you only enter 11 characters, add where you only enter 10 chars etc... It's over 22 million
Gee, a portable cable cutter at a decent price, while metal prices are high. What could possibly go wrong?!
So what happens when the lock's battery dies and you are not carrying a spare, or perhaps you have a spare battery inside whatever it is locking?
For nearly $500, not being able to cut steel cable makes that cable cutter an overpriced toy.
The march of technology never sleeps!
