I just bought a bottle of this the other day from Whole Foods ... I am pleasantly surprised and actually was doing a search to see what other people thought and stumbled across this post.. I have not tried the recipe floating around the net, my review is just from the pre mixed bottle.

Not too sweet at all, and I am very sensitive to very sweet tasting things. It tastes like a very well made margarita to me and I would buy more... you can smell the tequila when you pour into your glass but none of the ingredients are overpowering. Two glasses in and feeling good. I would recommend you try before commenting. :)
