A must for my coffee station. Great taste and makes me miss a cafe latte a little less. Love the taste of all four.

Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4)
Not using these syrups in coffee or drinks, just on muffins, breadsticks and ice cream. Here are the individual reviews from best to worst: -Caramel: almost perfect creamy pure caramel taste. Only flaw is I wish it were thicker. 9/10. -Dark Chocolate: has that classic slightly bittersweet dark countenance. You can almost taste a pleasant burnt cocoa bean flavor. Only flaw is that it is a bit too thick. 8/10. -Chocolate Caramel: not a perfect 50/50 blend, tastes more like a 70/30 blend in favor of caramel. Consistency is perfect, just the right thickness. 7/10. -White Chocolate: doesn't taste like WC whatsoever. It tastes like sickly sweet birthday cake icing in liquid form. Worst of all it is runny with no thcikness. 4/10.

Yummy
Flavor Name: Butterscotch
I'm very picky about taste, especially the coffee syrup. I have tried several and most do not even taste like the "name" on the bottle. I decided to try this one and it is so good, it tastes like butterscotch. Mmmmm The pump works fine and 2 squirts is perfect.
