I tried Miller Chill when it first came out, and really didn't like it -- I don't think it was the salt aftertaste others here have noted, but rather that it seemed like I could taste the Splenda-ish aftertaste of the additive.
I generally can't stand Budweiser products -- I get a headache even thinking about drinking a Bud -- but my bartender sister-in-law told me I needed to try the Bud Light lime. I thought I was in for another disappointing experience, even though this is coming from the girl who puts limes in her Amstel Light. When I tried it, I was surprised to find that I really did like it. It was actually quite decent.
(Of course, I won't be saying that tomorrow as we host our annual Jimmy Buffett party, since there will be Coronas and margaritas aplenty. But as a "quick swig after/while mowing the lawn," I thought it was good.)
