I love love love these drops. They make my water taste excellent and keep it interesting enough to drink several bottles a day. I love the variety of the flavors and how refreshing they are. Some have a stronger artificial sweetener taste, and some taste chalky/vitamin-y if left out for too long. But all in all, I am really enjoying these drops, as is my 5 year old daughter! The reason I can't give 5 stars at this point is that the customer service is lacking. The response times have been crazy long, which is understandable during a busy season. But what isn't acceptable to me is that some of the replies seem to be a generic response that doesn't address my specific concerns. It seems that once you get a hold of a representatives attention, they seem to be more helpful...but it's taken a super long time to feel heard. If there are no issues with your order/product, then all is well!
