Talk:Super Weapon Renewal Kit/@comment-3285517-20120625224834

Here are the theories I've heard so far:

1. The only possible durations are 90 days and permanent

2. There is a significantly higher chance of getting longer durations...

3. 180, 270, 360 day durations and increased chance of permanent

4. Can be used more than once

5. Gives something extra besides just renewing the weapon
