I get all my timed rewards after my last life, so never get to use them.

30 minutes of a reward only can claim after my lives are gone, so they r useless. 

Hi there, @Kflesh!  Welcome to the Community!

Don't be surprised! We all get that which is the reason why people here hate Timed Boosters. If you get them on Sugar Drops, you don't have to claim the rewards right away.

Hope this helps! Please let me know if you have questions or concerns!
