i received my first fuel cell in the mail today, the Max Fearlights. to be honest the reason i bought them is i saw them cheap on ebay and i love my Max Fearlight Holbrooks. i wear those quite a bit (they go great with my Chicago Bears jerseys on game day, too bad we suck this season...). it will be nice to display the two Max Fearlight frames together when i am not wearing them. i think i am picking up a second case this weekend, but i threw them in with the Holbrooks for now. i do have one other fuel cell on the way too, the smoked gray ones that were 35 bucks on the vault website.
