i had one the last buy1get1free go around. they really aren't THAT much better than their regular burgers -- I prefer the taste of even the .99 wendy's bacon cheeseburger to this (although of course that is smaller!). FYI I got mine at the driveup * dind't eat til I got home 10 mins later, that may make a difference.
just one guy's opinion. FYI I am an infrequent fast-food diner, I actually cook semi-elaborate meals daily (stiry fry, using the -- gasp! -- oven for something other than pizz, all that). if you do FF a lot, you might as well try it though.
