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.

Tastes good
Flavor Name: Butterscotch
I like the butterscotch taste. It’s really good with caramel coffee. The pump isn’t exactly smooth so it splashes a bit. When you first insert the pump into the bottle, be sure the pump is twisted into the open position.
