Ew...I love Canada Dry and Schwepps, and I decided to try this brand because it was cheaper and it looked authentic. Not sure how the regular (non-diet) kind compares, but this tastes so diety--it's gross. I usually drink diet soda and don't mind the taste of diet coke, diet dr. pepper, diet sprite, (other diet gingerale, too) but this is REALLY GROSS. don't get it! You can definitely taste the ginger, but the overly saccharine taste ruins it.

I didn't care for this drink at all.  It's almost like eating a sweettart in liquid, carbonated form.  My husband and oldest daughter felt the same way, but my 13 year old liked it.  It is 100% juice though, which is nice to see in a carbonated beverage.
