Baja Bob's drink mix

Anyone tried this:

Any good? I understand it might be easy to make a passable sugarfree replica of the regular drink mixes out there, but what about to the refined palate of the tikiphile? If it's slightly worse than bacardi I'm not interested, if it's slightly better that's worth it, know what I mean?

I tried the Mai Tai mix. As you could assume, it just wasn't quite right. I checked the ingredients afterward and just kind of scratched my head. One culprit is the use of a certain low-carb sweetener -- That aftertaste was pretty bad. Still, if you have certain dietary concerns this might be your mix. The photo of Bob on the label is priceless nonetheless, or at least worth the $5!
