Nickel Keychain (tested 2 months)

After 2 months of use, it fulfills its role:
- No cap to protect electronic circuits but the metal casing protects well for now;
- The carabiner is super convenient for dropping the keyfob in 1/4 second or so.

A note however:
- Heaters can be more than a conventional key? But OK;
- Fast but not supersonic;
- Rigidity of the junction Keychain / carabiner can not be perfect? But for now no problem.

EDIT: after 12 months of use, despite the dissatisfaction of many comments on the quality of this key to the amazon site, I see that I can be in luck because it still works nickel. I will update when a new break ...
