cheap and nasty do not buy
this lock is cheap and nasty and is really stiff to actually use. It is a waste of money and i would recommend against buying it

Gives me peace of mind.
Works as intended.

Simple and useful
Cable twist is very sturdy, maybe a little too much as it's sometimes hard to manipulate. Perfect to secure a spare tire on a trailer. See picture for actual item.

Cheap, Solid, Key form factor, Simple. Perfect 5/5.
1. Cheap - enough to buy two - one for a friend. Perfect 5/5 2. Solid - Really hard to clip, steel cable - good luck snipping or cutting. Would take large bolt cutter. Perfect 5/5 3. Key form factor. Fast 3 second lock or unlock. Coils for easy tow or pack it up. Long when uncoil to lock how you want. Perfect 5/5 4. Simple. Unlock a combination lock which is slow and also flawed prone to bricking when resetting the code, this is two key, could leave them in different places and since you have two, easy immediate use with no training or imperfect instructions. Perfect 5/5 Great, affordable product overall. Hard to ever be dissatisfied with these.
