Night shift worker! Switched from coffee to Zipfizz because it gives me a boost without the stomach issues. For me it's a cleaner feeling lift. So recently I found an empty tube in my box and sent an email to customer service. I received a response in less than 24 hours. They sent me a replacement plus a couple extra. To me that is great customer service . Thanks Zipfizz!
