My coworker was raving about these a while back. He buys big bottles, multiple flavors, even buys the pumps for them. I bought a few small bottles so I could try them and was unimpressed. I understand there are uses for the syrup other than coffee but how much syrup do you need? I like my coffee creamy. I can't just add the syrup.
My mother loves them, too, and buys me pumpkin spice each year. I prefer the sugar free kind, although I'm not thrilled with fake sweeteners either. It's fine, I use it. But I like using cinnamon oil better.
