They say they are going to be moving to all-malt soon, why they couldn't do that from the start of their new facility, I don't know. I've tried all of their styles, they used to also offer a red, a brown (which are supposedly coming back too) and a light lime. They ranged from awful (light lime) to "well that's not bad for the price" (brown).
I found the lighter beers to have more of an off-flavour (sorry I don't know what it was), perhaps the darker ones just covered it better. It's certainly not craft brew, but when it was $4/bottle (I think it's gotten more expensive) it was something to try for the hell of it. If you brew your own, I can certainly see why you wouldn't enjoy this, unless you're just curious to see what's out there.
